Allen TRULL I and Stephen TRULL
Stephen Trull was listed on the 1790 census as a head of household living in Anson Co., NC. I believe this Stephen Trull could have been the father of Stephen Jackson Trull (born 1815, the last of 10 children). An Allen Trull was reported on the 1800 census as a head of household also living in Anson Co., and there is a Stephen Trull noted again as head of household on the next line as well. According to WikiTree, Stephen and Allen were brothers - and had a third brother named Solomon as well. This info is said to be from an unsourced family tree handed down to one of Solomon Trull's descendants, Janice.
On the aforementioned 1800 census, Allen Trull's household is noted as having 1 white male under the age of 10 and 1 white male of 16 years, but under 26 years. There are also 2 white females under the age of 10 and 1 white female of 16 years, but under 26 years noted. This suggests that particular Allen Trull (Allen Trull I/Sr.) would have been between the ages of 16 and 25 in 1800. The Allen Trull that married Millie Price (Allen Trull II/Jr.) died Sept. 16, 1847 at 43 years old, according to probate/will records and a death notice published in The Charlotte Journal. This suggests he was born in about 1804, and seems to support that the Allen Trull on the 1800 census is not the same individual who died in 1847.
