My mother and I have worked off and on with Catherine for some time and tonight I thought we were indeed related.It looks like we're not but will post what I've found in the hopes that it will help someone else. I worked backwards on this line to come to these conclusions. In 1860 my ggg grandfather John Collins in listed with Catherine Stringham and Elizabeth York in Pottawattamie IA.We keep thinking that he might be related but have no info on his parents. In the 1856 Cass IA census p 4 house 31 is HG Stringham and family (Catherine's son)house 32 is Stephen and Catherine with William, house 33 is PT Stringham and family (another son of Catherine) house 34 is Joshua and Elizabeth York.By 1860 Catherine Stringham and Elizabeth York are living together and in 1870 Pottawattamie IA John Collins has married but the two women are still together a few houses away from him.So I thought with them just a few years apart both from PA and living together they might be sisters and it appears they are.I found the marriage record of Catherine Trover to Stephen P (Peter) Stringham 1/25/1817 in Washington Co IN.I then looked for Trovers in IN.1820 Mitcheltree Martin IN is Leonard Trover.I went back to 1810 and he's in Campbell KY with girls matching their ages and in 1800 he's in Sewickley Beaver PA and they said they were born in PA.Then I noticed that in 1810 Joshua York is also in Campbell KY.I suspect that he and Elizabeth married there between 1810-1817.In 1815 a Nancy and Delila both marry in Campbell KY and Leonard Trover was the bondsman for both. Nancy Trover married Henry Gardner 6/7/1815 Delila Trover married Harvey Manning 8/11/1815 I assume Leonard left Campbell KY and located to the Washington IN area shortly before Catherine married there and then he moved on to Martin Co IN. Martin Co IN Land Purchase Records show: Leonard Trover 10/9/1818 (later lost land) Stephen P Stringham 10/9/1818 (later lost land) Henry Gardner 12/10/1818 (later lost land) Harvey Manning 1/15/1819 (keeps land and stays in Co for decades) Given the circumstantial evidence I think it's safe to say that Catherine Trover was Leonards daughter.I wish I could find a marriage record for Elizabeth to Joshua York to prove she was a Trover.Perhaps the most compelling proof of her maiden name is that in 1850 she has two children living with her- John and Martha Trover.These must be her neice and nephew. I had hoped that my John Collins might tie in if his mother was Catherine and Elizabeth's sister but it doesn't look like it.In 1810 there are 5 females in the house. 1 is 10-15, 2 are 16-25 and 2 are 26-44.I think in that range that there is a daughter at the younger end and a mother at the older end.If there are only four daughters then they are- Elizabeth, Catherine, Delilah and Nancy. If anyone knows how John Collins came to live with Catherine and Elizabeth I would love to know.
