I have a Sarah Sophia Monteith born 8 May 1823. I do not know where. However, she married Nahum Ball Gates and had at least one child William Nahum Gates who was born 17 Oct 1857 in ELYRIA Ohio. There must be a connection somewhere. Many of my Gates relatives are from ELYRIA.
I have no info on Sarah's parentage at all.I do not see how she could be the Sarah who is a daughter of Rev John, as she married a Gates, not a Harris. Hmmm.
