Barbara, in A West Wind to East Bay, there is a reference for for Flora MacIsaac, b. 1846, who married Joseph Morrison (Angus). Flora was a daughter of my great-great grandparents Aonghas MacIsaac, (b. PEI circa 1807) and Isabella MacDougall. Aonghas, was the first son of Donald (Domhnull MacIsaac), who settled in East Bay via PEI. His father, Roderick MacIsaac, was born in South Uist and died on the voyage to PEI in circa 1792. Roderick was married to Flora MacNeil of South Uist, who died in Rock Barra, PEI, in 1813.
The same book references a Joe Morrison (b. 1848) who married Flora MacIsaac. Joe's parents were Aonghas Mor (b. Scotland circa 1802) and Mary MacMullin of North Side East Bay (b. circa 1854).
