There was a Maria Atkins, father Thomas,registered 29 DEC 1816India Office Ecclesiastical Returns-Bengal Presidency, , , India (from IGI)
and a William b 1837 to Sarah and William. He died 11 NOV 1905
There is nothing else on the IGI that seems relevant. Wish I could help more, but these are so difficult. I have four convicts and one more that probably is, but I can't find her under any of two names I know her as. Sigh. Can't even find her convict records, so no idea where she was from.
