Thanks everyone for providing responses to my question. Anne, Thanks for this info from NEHGS vol 80. I wonder to which deceased member it applies, perhaps 1 of the authors of the following book. There are 2 books "The Genealogy and biography of the Connecticut branch of the Churchill family in America" by Samuel Joseph Churchill publ Lawrence, KS, 1901 and "The Churchill Family in America" complied by Gardner Asaph Churchill, Nathaniel Wiley Chuchill and George M. Bodge, publ by the family of Gardner A. Churchill, date 1904 handwritten.
The 1901 books says Joseph marr Mary Toucey May 13, 1674, without any further into on Mary. The 1904 books says "married at Wethersfield, May 13, 1674, Mary --- ... long and diligent search has not brought to light the surname ... She survived him and lived to advanced age. She is mentioned as "Widow Mary, Senior," in the settlement of her son's Nathaniel's estate, April 2, 1728."
So I plan in time to replace the wife Mary Catlin-46 with a Mary Toucey or similar spelling but if someone else wants to proceed to do so that is fine with me. I paged back through the change pages it it looks like Mary Catlin was added as wife as the same source "One Branch of the Booth Family" 23 August 2013
