Don , Thomas Thursby was married to Mary Ann Baxter in the June Quarter of 1881 in the Bethnal green District 1c - 631. If you want the certificate that will get you it. Polly was her nick name. Thomas was the son of John Thursby born in Badwell Ash Suffolk England in 1818, his wife was Susan .The lived at no.4 New Street St Luke Finsbury London for a number of years . Susan died between the 1871 census and the 1881 census. On the 1851 census his name is Thomas Thursby for some unknown reason. in the 1841 census for Badwell Ash John Thursby is spelt Thorsbey . Also a Joseph Thorsbey is living with Robert & Mary Coatbridge and daughter Sarah with wording at the side of his name "same family" I`m not at all sure what that means.You can obtain all the census years from 1841 to 1901 except 1891 ,that seems to be missing. Good Luck Ron Thursby South Aussie.
