Hi, are you still looking for Thomas Gregory's father? I did a little digging around and as you know your Thomas was born in England. On the 1900 census for Plymouth, location Hingham it says his birthday is May 1858. Also on the 1900 census for the same area there is a Thomas Leigh born England age 69 born England. I checked out this Thomas Leigh on the 1880 census Plymouth location Hingham and there is Thomas Leigh Sr, wife Ellen with son Thomas G Leigh age 12 born England, plus other children. If you do not have this info let me know and I'll down load all the censuses and send them to you. No kin Jane.
