Hi there, My family is mostly Argyllshire, but I've run into the same thing. For years, my Dad could find no marriage for his maternal grandparents, Neil MCKINNON & Ann PATERSON. When he finally found it, the groom was listed as Donald PATERSON! Funny, Neil did have a brother, Donald, who was a witness to the marriage - maybe therein lies the mistake, with the registrar mixing up the 2 MCKINNON brothers? Moving along 1 generation, Neil & Ann's eldest son was Donald MCKINNON, born June 19, 1884, on Tiree. Donald was always known as "Dan" to family. He immigrated to western Canada in 1905. His WW1 attestation papers in 1916 list him as Donald James Paterson MCKINNON. By his 1964 death, his name had completely evolved into Donald James PATERSON-MCKINNON! No idea how that all came about. Have had great struggles in the past too with Agnes & Annie. In some branches of my family, they seem to be completely interchangeable. I had a cousin born Annie Kerr JOHNSTON, who was Agnes on her marriage reg., but Annie Agnes at her death. She married a cousin of her own & I've seen her listed as Annie Agnes Kerr KERR! Has anyone seen Sarah & Marion as being interchangeable? My Gaelic speaking Dad says it's because the names in that language are pretty similar. Oh what fun!
