This descendant of William Lowe (via William's son John) has been researching the family I posted. In one of several genealogy forum posts, she wrote:
"My William Low(e) was married in 1828 at Jefferson Co, OH to Mary Sanderlin(e). Trying to find more information on them. They had 4 children born in OH. Benjamin 1832, Joseph P. 1834, David 1836 and Sarah J. 1838. They moved from OH to IN. Had two children born there. William H. 1840 and John C. F. 1842. They they moved to WI. Had two more children Cyrus L. 1845 and Mary E. 1848."
Note that one of the census records I posted had a Sanderlin child. This person seems to have been diligent in seeking information and may be an excellent contact for you (in addition to the usual routes of seeking public records, as already mentioned).
