I'm looking for a possible John Chiles family; he was born in Chatham, Kent, in 1762. His assumed daughter, Elizabeth, was married at St. George's, Bloomsbury in October 1808 and was not a minor (so was born after 1787).
My 2nd great grandfather, Richard Edward Cardin was baptized at St. George's Bloomsbury in October 1805 but his siblings born in London (he was born at sea, his parents and 2 older sisters returning from India) were baptized at St. Luke's, Chelsea, so I'm thinking they were staying with their mother's uncle's family when they first returned and then found a place of their own later.
