Quite a few people seem to have information on this family. Does anyone have information about a Mary Slark born c. 1840, probably in Berkshire, though she had a daughter in Marylebone in 1867? She 'married' William Bird (he is the father of her daughter at least)but I can't find traces of this marriage. My Mary Slark may not have come from Berkshire - there was one born in Bristol around 1837, don't know if she was related to the Mary Slark in Swindon.

Thanks
