Hi Miranda,
I think i have found a link between your "Mary Richardson" and my great grandma,i think they were sisters,
My great grandma was Jane Richardson,who in 1878 married a Thomas Hall of Warcop,
Their eldest daughter (my grandma)was Sarah J Hall born 1879 who married a William Richardson (my grandad) in ??, I am positive that this was her second marriage but cannot find anything about it,
Sarah J Richardson died in 1923 giving birth to my mother,
William Richardson died around 1955 ish
I can trace the Hall side of the Clan but have drawn a blank on my Richardsons,
Regards BrianT (totally confused)
