Hello Johngirl,
I'm a relative of yours (Descendant of Richard Kemp and Mary Deal - on my father's side), and I've not long been researching both said ancestors.
Though I've found some relative info on Richard, I'm stumped when it comes to Mary.
Pretty much all I've found is that she was Irish, her crime, OB sentencing and subsequent deportation on the Janus, then the Princess Charlotte. I have visited her grave site (and as far as I'm aware, Richard is buried in an unmarked grave next to her), but it all seems to dry up from there.
I'm just wondering if you could fill in the huge gap from there on in, and whether you have any more information on Richard and his connection to St Mary Cray, Kent.
Kind regards,
Your cousin somewhere along the line...

P.S. I'm new to this site as well and I didn't know how else to contact you.
