Hi Roger
Many thanks for your help. Yes, that is the family. It makes for challenging research when the same first names of Thomas Irvine keep getting repeated through the generations.
Many thanks for the tip about the Falcarragh facebook page. I will definitely be joining that. I have had a DNA test done through Ancestry and a couple of the descendants of Mary Jane & Thomas McClintock show up as matches, along with descendants of some of Mary Jane's other siblings who emigrated to the USA. I'm particulaly interested in finding other relaitons who may still live in Ireland
In case others come across this post, the children of Mary Jane McKinley and Thomas McClintock are::
Thomas Irvine McClintock (1907-1945) married Edith Evelyn Glew. Died in New York
John Charles McClintock (1909-?). He also seems to have emigrated to the USA
George Francis Alexander McClintock (1911-?) married Catheriine Spratt. At least 5 children all born in Donegal - including yet another Thomas Irvine McClintock!
Mary Violet McClintock (1914-1981) married Francis Alcorn in 1938. They had at least 5 children all born in Donegal
Harry Reid McClintock (1919-2001) died in Canada
