Found 1861 Census Township Osprey/Grey County a Robinson Gachlin or Gacklin or Jacklin (42) with the following children: Ann (19), Elizabeth (17), Frances (15), William (10) and Joseph (8).

I am a descendant of an Ann Jacklin (1841) who, I know spent a number of years living in Parry Sound. Trying to figure out more about her. I believe she was married to John Cameron, Joseph Walker, and James Chapman. Any of those fit with your tree?
