It is unknown when the family immigrated; on a 1920 census the immigration year is listed as 1853 and Naturalization in 1860. I've searched ISTG and Castle Garden records for for 1853 and cannot find Youts or any variation.
I'm figuring the 1853 date is a guess (as some of the information throughout the census' found have incorrect data).
The first census I find Mary (mother) and kids on is 1860 in St Joseph, Indiana with husband John Kelly.
No dates or departure points have been found or are known at this point by any of the family. There are a few Youts lines in America; one Youts family settled in Beaver, Pennsylvania - that line is not connected (at this point).
Any ideas how to find information?
