You seem to be jumping all over the place once you find anyone named James or Elizabeth Beattie but still haven't indicated if the 1901 Belfast census record is for the correct couple Probate of the Will (with one Codicil) of James Beattie late of Follem Big County Fermanagh Farmer who died 18 March 1904 granted at Armagh to Thomas Moan Farmer.You can view the wording of the Will (2 pages) rather than guessing-http://apps.proni.gov.uk/DCAL_PRONI_WillsCalendar_IE/WillsSearch.aspx
I am pretty sure this is the couple
