Hit a road block on my 3rd great grandfather and 2nd great grandfather. I have censuses saying where they last lived but cannot find anything like death notices or burials of any kind. It is like they vanished! 3rd great grandfather was born in 1800. It says in Pa. But census says he lived in clarion county. Clarion county wasn't formed until 1839 by 2 parenting counties of venango and armstrong. So was he born in venango or armstrong county or somewhere else and moved there in about 1839 when clarion was formed. His name was JACOB HALLMAN. His one of 4 sons was my 2nd great grandfather. His name was SOLOMAN HALLMAN. Soloman has a couple of last name variation spellings like HOLLMAN and HOLMAN. His last known residence according to census was boggs township /clearfield county. I hope someone can help? Thank you!
