Appreciate information, on James/ Hugh & Elizabeth and Hugh & Jane, had no information on them when they were still in Ireland. I have only recently joined Ancestry.com my information comes from Scotland's People.
I wondered if you had seen Thomas Boyce's baptism information as it shows he was actually born on 12 May 1850 and baptised in 1854 in Dalry.
Jane Murray Boyce was born at 7am on 14 Oct 1872 in Smith Street, Dalry
John Boyce (whom I am descended from) remarried after Alice Lowe died and had 3 sons with his second wife Christina Keenan
Thomas & Jane also had a daughter Elizabeth (possibly named after Elizabeth Hamilton) who was born at 6am on 27 May 1879 in North Street, Dalry
Hope this information helpful, thanks again for your imput.
