Glancy and Canon Families Pre-1855

Researching Glancy and Canon families from Inver Parish.

William Glancy son of Patrick Glancy, farmer, and Rose Canon.

William is my GGGrandfather.  Attached is his marriage record from Scotland.  Looking for current family connections and for pre-1855 information on the Glancy and Canon families in Inver Parish, Donegal.

Also have some Tithe Applotment info but do not know if I connect to any of these.
