searching for information James Sherman & Annie Gawley

Searching for information on my 4 gr grandparents James Shearman (Sherman) (c1780-1871) & Annie Gawley (1793-1875) who came to Ontario Canada about 1823 with 2 children. Annie's brother Andrew accompanied them. According to Annie's death document she was born in Clones, Ireland. Another source says Co. Fermanagh. An elderly relative many years ago said they were from Gawley's Gate (a townland?). In Canada they were Methodists. Any information would be appreciated.
