Tried to reply to you directly but the message was returned as undeliverable.Short answer is that McIlravey/McIlravie/McElravey is the most common form used from the early 1800's to the 1940's.I trace my McIlravey family to Ireland where James was b. 1844 to James and Jane (Pim).In 1866 James m. in Greenock, Fanny Smith; they moved to Johnstone about 1872 and resided there until they immigrated to Grafton, MA about 1894.I know that their son James m. Mary Andrew 1890 in Johnstone and they had 2 children; James and Malcolm Andrew.I cannot find a death or marriage record for these sons but I did find a death record for a Malcolm, son of James and Mary (Armour) in Johnstone.There was a Mary Armour b. 1889 in Johnstone and another b. 1890 in Johnstone. The ages would appear to be correct.I'm trying to determine if indeed this is the right family and if there are any family members still in Scotland.It is interesting because James, son of James and Fanny, b. 1867 died in Massachusetts and was listed as single.Not sure if he deserted his family; if he left when they matured or if they had all died young.Appreciate any help you can provide.
