Hi Marcella,
I found an Archibald Beatty married to Jane Robinson 25 Jan 1861 at Sallaghy COI, Galloon, Fermanagh, his address is given as Crockerahoas, Galloon, his father James Beatty (Labourer). Jane's address given as Derrycorby, Galloon, father is William Robinson (Farmer). Both ages are shown as "Full". I can find no reference to any children of theirs in the Sallaghy Birth/Baptism register entries.
There are also references to Archy/Archibald Beatty's in the 1830-1844 Galloon parish registers one is married to Letitia Guy the other refers to an Eliza Guy. likely to be the same couple, married 3 Aug 1835 and some children shown. Also 2x mentions of James Beatty marriages one to Margt Armstrong on 28 5 1839, the other to Ellen Levingston on 24 9 1841, no children shown for either couple.
There are also over 50 Beatty names in the Gallooon OPR 1798-1830. Among them a burial for Elizabeth Beatty age 35 of Sligo, Co Sligo.
I know there are Beatty's scattered all over, but you never know if people post what they know, something may well match a small snippet of what you already know.
Good Luck
Rusty
