I have only looked at census records, online indexed record info and some baptismal registers.I have been collecting this kind of data, but have not had time to put all of the pieces together.I have seen a William in several records.
The William I refer to here is the son of Louis.I cannot find the link (yet) to this Louis and Lewis/Louis/Aloysius who lived next to him, but I think they are probably father and son. (Louis also has a son whose name is spelled Lewis in the census.) Assuming this to be correct, Richard is a younger son from the second wife of "Lewis", and would be William's uncle.
In the 1870 Harrison Twp census William age 23, a sailor, is living with Louis. There is a Wm. who married a Mary Thomas in 1873.
Is this your William?
Are you looking for living relatives or earlier ancestors?
I have more info on the earlier ancestors if that is where the interest lies - if you do not already have that information.
