The Boyd family tree starts with John Boyd who married his cousin Margaret Boyd c1750 and moved from Lismoyle to Collins c1784. They did have a son Thomas Boyd born c1787 who moved to Killykergan but he married Jane ? . Their son Thomas married Morrow and went to Boston, Mass. so definately not the same family.
Found out last night (still going through old papers and checking with other resources) that Robert "Robin" Heaney had a brother Thomas so Robert can't be a brother of William, Ann & Thomas.
Robert "Robin" Heaney married Jane Wallace, His brother-
