I ran a quick check on www.registryofdeeds.com
Create an account--it's a useful primary doc tool.
It's Hancock Cty.'s registry of deeds portal; and you can backtrack Margaret & William's real estate & mortgage in Hancock (purchased from Young-Stratton clans, which makes sense--historically speaking).
Margaret sold to Wm. & Margaret Kendrick in '72 (Book 1158|Pages 528-31).
Or, do searches: collins, william g. and collins, margaret e.
See what ensues.
