Hi Judie.
I have Isaac Mills in the 1817 Shore District census.This
would be Kempt Township.He is shown with 2 boys,1 woman and 2 girls.This would
appear to be your Isaac who has the two sons.One son was Isaac born in 1821 who
m. Eliza Lake.Isaac and Eliza had Henry Pope MillsBut I also have Amistad Mills
with two sons in 1817 so he may be the father of Isaac.A look at the childrens
names may help to solve the puzzle.Does this sound correct?
The search goes on,Frank.
