Hello, In 1840 my 3xgreat grandfather Thomas HINDMARCH married Margaret MYERS (born as Margaret MILNER in 1802 in Sunderland) in the Parish Church, Sunderland. His profession is recorded as "Superintendent of the Durham Railway" and his address Thomas Street. Unfortunately Thomas is not with his wife at North Quay, Monkwearmouth on 1841 census and there is nothing to say whether Margaret was a widow or not. I believe three children Margaret, Elizabeth & Thomas (born c1843-1844) are his and he therefore must have died between 1844-1846 when his wife Margaret married William GIBSON a pilot from Monkwearmouth. Any help in researching any of these names would be appreciated. I am particularly interested in finding more about Thomas' profession as "Superintendent of the Durham Railway". Also, does anyone know where Thomas Street was or is? Thanks for any help, Regards, Mark Etheridge.
