"The next son John, (born 1818), was presumably the one who married Ellen Mavor and went to Canada."
Subsequent investigation has shown this was incorrect. My confusion was caused by there being a John Younie, son of John Younie and Anne Collie, unmarried, age 33, at Rafford Farm in the 1851 Census and then a John Younie, age 42, married, with a wife, Margaret, and a 17 year old daughter, Mary Younie, there in 1861. My initial assumption was that these must be two different John Younie's, the first one being the one who married Ellen Mavor.
However when I looked at the 1863 Marriage Certificate of Mary Younie it stated that although John Younie was her father her Mother was an Isabella Nicholson of Dyke, (deceased). Actually Mary Younie had been at Rafford Farm in 1851 also, but described as a Granddaughter of John Younie snr. with no indication that she was John Younie jnr's illegitimate daughter.
Four years before his daughter's marriage John Younie, Batchelor, age 39,(actually he was almost 41) had married a Margaret Anderson in Forres and on his Marriage Certificate he is shown as the son of John Younie and Anne Collie. John and Margaret had only the one child, a daughter named Margaret Elizabeth born in 1868. They continued to farm Rafford Farm until the 1880's.
This John Younie died at his daughter Margaret Elizabeth Henderson's house in Edinburgh on 23rd. Jan 1906 and on his Death Certificate it again confirms that he is the son of John Younie and Anne Collie.
This, I think, proves he is not the John Younie who married Ellen Mavor and went to Canada.
