Hi,
I read with interest your posting regarding John Murphy (m. to Jane Ward Murphy) and his children, one of which is your gggrandfather. I have a Edward Ward Murphy the son a John Murphy, and although his mothers name is not the same as what you have, it is interesting that "my" Edward shares the last name of this Jane in your line. I have further information on Edward if this is of interest. My Murphy's started out in Canada, this Edward was married in St. Sylvesters Quebec in 1843.
