Hartzell, David A - Va - r 3 b Main & Walnut
From some investigation, I take this to mean born in Virginia, residence on 3rd between Main & Walnut.
This must be the D. A. Hartzell in the 1860 Hamilton County Ohio Census.
NEW QUESTION: What if Adam and Christina died about the same time in the cholera epidemic, and if there was a son Daniel, that he died also?

The mystery of an old leather-bound Bible now belonging to Ray Bunyard, a descendant of David Hartzell, may finally be solved. In light of recent discoveries, the following provides useful clues about the unidentified son of Adam & Christina Hartzell, born 1800-1804, between Leonard (1799) and David (1805). The 1810 Franklin County, VA Census shows 3 males under 10 years old. By ages of the unidentified son in the 1810, 1820 and 1830 Census, he would have been born from 1800 to 1802, in Virginia.

See genealogy chart below for names of people.

David Hartzell's granddaughter Minnie Alberta (Hartsell) Hart inherited the Bible, probably after her father James Alexander Hartsell died in 1910. She had married in 1902. In the Bible, Minnie wrote "Property of Great Grand Father Hartsell". Someone else, maybe James' wife Sophronia, wrote "From Daniel Hartsell to David Hartsell to James Hartsell to Minnie A. Hart" (after 1902). For many years, it was assumed by some of the family that Daniel was David's father. I thought maybe a cousin, or that he wasn't a Hartsell, like his Indiana neighbor Daniel Guise. What seemed like unreliable family folklore now seems to be an incredibly important clue, both for the ancestry of David Hartsell, and for Adam Hartzell's unidentified son.

Minnie most certainly meant HER great-grandfather. She could have but didn't write "Great Grand Father Daniel Hartsell". It seems she, like everyone else, did not know his given name. So, we must assume it was Adam Hartzell. Adam is presumed to have died around 1832, thus David Hartzell's children, born after that, never knew their grandfather Hartsell. David's grandson William Webster Hartsell, a lawyer, surely knew about his sister's Bible, and knew that Daniel was not David's father, because of his "Ferdinand" notes* told by his aunt Sarah (Hartsell) Walden. Plus, David's great-grandson Donald V. Hartzell, born 1912, who researched family genealogy, did not know who Daniel was. It would make the most sense that a brother named Daniel gave David their father's Bible, and with a reason to do so. A Daniel born about 1801 in Virginia, with a reason for being hard to find. Plus, David's children were far more likely to remember an Uncle Daniel.

In late 2006, after searching via ancestry.com all U.S. 1850/1860 Census records for a Hartsell (Soundex spellings) born in Virginia 1799-1805, I found only one. He was D.A. Hartzell, age 58 (see NOTICE above). The census was taken June 16th, so he was born in the second half of 1801 or first half of 1802. He was in Storrs Township, Hamilton County, Ohio, in 1860. That township is now Lower Price Hill, in southwest Cincinnati, on the Ohio River. He was 40 miles south of Adam's 1830 Ellerton, Ohio homesite. Again, he was born in Virginia. He was unmarried, which made him hard to find, not being head of a household. He was keeper of a boarding house. 99% of Hartsells I've found with a name starting with "D" back then were either David or Daniel. If Adam's son, he would have to be Daniel. He has not been found as head of a household in the 1830, 1840, 1850 or 1870 Census.

In the 1830 Census for Jefferson Township, Montgomery County, Ohio, in the household of Adam Hartzell, there are two males 30-39 years old. We had thought they were live-in farm hands, but Adam didn't own land, so it didn't make sense. Since David, age 24, (and Daniel?, age 28) were unmarried, it is more logical that they were still at home. After noticing many corrections on that census page (see image in "Evidence for Ancestry of David Hartzell"), it is very easy to believe the census taker mismarked 20-29 years old. If the other male was Daniel, it all falls into place. Daniel being the oldest of the two, "inherited" the Bible when their father died. Nothing was written in the Bible as customary, so it may not have been a "coveted" family heirloom. Since Daniel appears to have never married, and having no heirs, he gave the Bible to David. David had children as of 1837. David lived near Connersville, Indiana until 1860, then moved to Illinois, and died in 1865.

* On the "Ferdinand" notes, it now seems Sarah Walden may have been recalling her grandmother's father, who could have been Ferdinand Zink/Zinck/Sink.
