Here is the list of unknown Flinchbaugh children born between 1800 and 1820:

1. Catherine Flinchbaugh (April 22, 1809 – February 23, 1887) married Adam Trout (October 7, 1811 – August 21, 1890)
2. Nancy Flinchbaugh (about 1809/1810 – March 1, 1898) married Henry Sechrist (March 27, 1806 – October 29, 1872)  They moved out west to Cambria County, then Allegheny County and finally settled in Beaver County.  More information on them can be found here http://files.usgwarchives.net/pa/beaver/bios/sechrist-henry.txt
3. John Flinchbaugh (born about 1810) married Elizabeth (lived in Conoy Township, Lancaster County in the 1850 census)
4. Jonathan Flinchbaugh (1840 census lists him as head of household in Hopewell Township, aged 30-39)
5. Samuel Flinchbaugh (March 4, 1811 – September 10, 1877) married Anna Mary Blouse (November 12, 1815 – April 24, 1888)
6. Elizabeth Flinchbaugh (about 1800 – 1838) married Solomon Reese (about 1794 – November 25, 1861).  Elizabeth and Solomon moved to Augusta County, VA by 1830.  DNA matches with several descendants of different children of Elizabeth and Solomon confirm that she is a Flinchbaugh, since no other shared common ancestors exist with the DNA matches.  (Updated below on 12/13/17)
7. Daniel Flinchbaugh (March 21, 1815 – December 18, 1875) married Mary Jane Grim (July 16, 1820 – March 22, 1906)
8. Elizabeth Flinchbaugh (September 24, 1814 – March 24, 1847) married Samuel Kreidler (December 15, 1817 – January 15, 1862)

Numbers 3 and 4 above (John & Jonathan) are more than likely the 2 youngest sons of John & Magdalena.  That leaves the other 6 to place with Henry (1779), Reverend Frederick and Frederick since Orphans Court records and wills verify we have the children of John (1771-1819) and Adam (1782-1842) all accounted for.  Census records indicate for Henry, Reverend Frederick and Frederick reveal they had other young children in their households besides the ones we have confirmed above.  The census records show:

• Henry had 2 males born between 1800 and 1810, 1 male born between 1810 and 1820, 2 females born between 1800 and 1810, and 1 female born between 1810 and 1820 (1810 census listed 2 males under 10 and 2 females under 10.  The 1820 census has 1 male under 10, 1 male 10-15, 1 female under 10 and 1 female 10-15).  We have John and Elizabeth, leaving between 2 and 4 children unaccounted for (1810 census lists 4 kids under 10, but we only account for 2.  The 1820 census lists only 2 children born before 1810, but we don’t know if the older children moved out of the house, died or were counted as under 10).
• Reverend Frederick should have 1 son born between 1805 and 1810, 1 son born between 1810 and 1820, 1 daughter born between 1805 and 1810 and 1 daughter born between 1810 and 1820 (the 1810 and 1820 census are consistent with ages for children). We have Henry K and Frederick accounted for, leaving the 2 female children unaccounted for.
• Frederick should have 2 females born between 1805 and 1810, 1 female born between 1810 and 1820 and 1 male born between 1810 and 1820. (1810 census shows 2 females under 10, 1820 census shows 2 females 10-15, 1 female under 10, and 1 male under 10).  We only have Christina accounted for, leaving 3 children unaccounted for.

Based on the information that is available, here is the best estimate of who the parents might be for those 6 children:

1. Catherine Flinchbaugh (who married Adam Trout) – either the daughter of Reverend Frederick Flinchbaugh or Henry.  Since Frederick had a daughter named Catherine, that eliminates him as the father.  She could be the female born between 1805 and 1810 in Reverend Frederick’s 1820 census, or she could be the under 10 counted in Henry’s 1810 census but was still counted as under 10 in the 1820 census (which is possible since census records didn’t always accurately record the age of children)
2. Nancy Flinchbaugh (who married Henry Sechrist) – could be the daughter of any of them, especially since we don’t know her birth date and can’t determine if she was counted in the 1810 census or not.
3. Samuel Flinchbaugh (who married Anna Mary Blouse) – either the son of Frederick or Henry.  We know Reverend Frederick isn’t the father since his 2 sons are accounted for.  There is a Samuel Flinchbaugh in the estate records for Frederick Flinchbaugh who purchased many items from the sale of the estate, as well as owing $30 on bond to Frederick for the purchase of a wagon.  Also, Samuel lived just to the northwest of where Frederick and his two other sons Jacob and John lived.  However, Samuel is buried at Bethlehem Stonepile Methodist Church.  Methodist is the English speaking version of the Brethren church, which is what Reverend Frederick preached in, while Frederick and his children remained Lutheran.
4. Elizabeth Flinchbaugh (who married Solomon Reese) – either the daughter of Frederick Flinchbaugh or John & Magdalena Blymire.  Reverend Frederick being born in 1788 is too young to have a daughter born around 1800.  Henry already had a daughter named Elizabeth who married John Godfrey.  This leaves her as being one of the under 10 females in Frederick’s 1810 census, but not counted in 1820 (due to possibly having already married and moved out).  John & Magdalena did have a daughter named Elizabeth born in 1798 and possibly be her parents, except the estate records for John list him having 7 children with Magdalena.  Six of those children were named as minors (John, Jonathan, Jacob, Sarah, Lydia and Catherine) and based upon the date of birth have identified that Mary Magdalena who married Jacob Geesey is the 7th child.  It could be possible Elizabeth wasn’t mentioned in estate records since she was already married at the time.  (Update as of 12/13/17)  As mentioned earlier, DNA matches between several children of Elizabeth Flinchbaugh and Solomon Reese and both my mother and her cousin Alan Laudermilch confirm that Elizabeth is a Flinchbaugh descendant.  In contacting one of those descendants, Theodore Miller, he allowed me access to review his DNA matches.  In reviewing those DNA matches, his closest Flinchbaugh matches were with people who were all descended from John Flinchbaugh & Magdalena Blymire’s known children.  He did not match any matches with people who were only descended from Frederick Flinchbaugh & Christine Pfister.  Based on this DNA evidence, I am now adding Elizabeth the daughter of John & Magdalena that was born in 1798.
5. Daniel Flinchbaugh (who married Mary Jane Grim) – like Samuel, either the son of Frederick or Henry.  If we can determine the father of one of them, then we know who the father of the other is by process of elimination.  Daniel isn’t mentioned in any of Frederick’s estate records, but he is buried at Lebanon Lutheran Church like Frederick and his sons Jacob and John.  Daniel lived in Hopewell Twp, closer to where Henry lived than where Frederick lived.
6. Elizabeth Flinchbaugh (who married Samuel Kreidler) – either the daughter Reverend Frederick or Frederick.  As mentioned before, we have already identified a daughter for Henry named Elizabeth.  Elizabeth and Samuel lived in Shrewsbury Township, which is closer to where Reverend Frederick lived and all of Frederick’s known children lived close to him in the Felton area
