The 1850 St Louis Co,MO census has a listing for the family of Jacob Anbbergan. It shows he was b in PA in 1817. I have tried variations of spelling for the surname and nothing comes up. No place in the USA. He was married to Mary Burns c 1837 and they had 2 dghts b PA: Emma E bc 1839 and Mary F bc 1846. They also are shown having a dght Margaret bc 1848 WI.
Is there anyone that has any idea of how this surname might be listed on the censuses for PA btw 1810 & 1840?
