Gordon's of County Armagh

[fgordon]

Can anyone help me find info on Joseph Gordon and his wife Mary Jane (her maiden name was McKettrick or McKittrick, etc). Joseph came to Canada in the 1850's with his family. Their religion was Primitive Methodist. They may have come from Marlacoo Beg, Mullaghbrack - as I have seen reference to a "valuation" list that contains a Joseph Gordon, but the late looks to be early 1860's and there is no doubt that by that time they were in Canada. Any help, hints or leads from anyone would be greatly appreciated!
Happy New Year!
