John,My great, great grandmother was Adelia Tibbits Ogden.She was the eldest daughter of John Powers Tibbits, sibling ofLyman Childs. The Tibbits family moved to Columbia California during the Gold Rush. Have you been to Columbia and seen the Tibbit's home?It is a part of Columbia state park.
I believe, but have not yet substantiated, that John Power's father was Oliver(Power)Tibbits born in MA March 26, 1773, died in Newark Ontario, NY, March 28, 1820.Oliver was the son of Caleb (Pierce) Tibbits and Elizabeth(Westcott) Power.I got this much information from Familysearch.org.The tree I found goes back quite a ways. I indicate in parenthesis the mother's family name.Although the dates and names sound like they could be right, Iam not sure however the names of their children.Sounds like we are on the same trail. Was Lyman your ancestor?Happy hunting.Please let me know if you can substantiate this data.
