My 3 x Grt Grandmother, Mary Travis, was born in 1756 in Misson, Nottinghamshire, England (close to Doncaster and the Yorkshire border). She had an illegitimate son, William (my 2 x Grt Grandfather) in 1782 in Misson with William Fisher but they did not marry. She married Edward Blyth in Misson in 1785 and I think they had a son in 1786 named John Blyth born in Misson. After that I have completely lost her. There is a possible death for her in 1821 at Finningley Cottage in Finningley (near Doncaster) where son William Travis lived, but I cannot find anything else. I would be very grateful if someone could help discover what happened to her and if that was where she died.

Caroline was my second great aunt and I would love to know what happened to her after she moved to Canada with husband George William in 1880s.

Can anyone help please with information about the Smith family who lived in Breen (near Castlederg) Co. Tyrone, Ireland ? Mathew Smith b 1806 d 1853 (Will exists), married Anne 1809 - 1869(?) and had son Thomas b 1830 d 1865 Strabane. He married Elizabeth McCormick b 1829 Tyrone. They had sons Mathew c 1861 (married Mary McCormick b 1861 Tyrone) and Thomas H Smith c 1862 (lived Liverpool). Thank you.

Mary Richardson and her husband are on the 1881 census living with married sister Caroline Fent (now Hare) and her family. Mary is "Married" to James Richardson b Jedbrough, Scotland. He is a blacksmith. I can't find either Mary or James Richardson in any other census living anywhere. I suspect Mary (nee Fent), who married Hercules Overton (also a blacksmith) in Hull in 1867, was not married to James Richardson - but where did Mary go after 1881? Or, perhaps Mary and Hercules Overton were both lying about their surname and place of birth - but why? Incidentally, I have not found Hercules Overton on the 1881 census anywhere else although I do know about him from 1891 onwards. I would be grateful for any help to prove who they were or to trace Mary Fent/Overton/Richardson.Please let me know if you need any more details.
