Hi everyone
Thanks for the replies.
It just seemed a bit strange when all the other family names were very plain - Richard, Sarah, William, Thomas, Mary, Ann, Jane, John & Mahala!
I found the 1827 Mahala's baptism but nothing subsequent - she is not on the 1841 census with the parents & other sibs. Perhaps, sadly, the "sick / feeble" definition was appropriate

Thanks again - I was beginning to think it was a Kentish thing [or is it a thing of Kent - I can never remember the rule about the Medway]

Regards
SandraC
