Searching for information to put the pieces together on the marriage and family of Albert Clayton KELLAM of Heron Lake, son of Dr. C.R and Mary Kellam to Susan NELSON of Heron Lake.

1880 Census places Albert (born NH) with family in Heron Lake.

1920 Census for Lynn, Essex, Mass shows Albert, wife Susan Nelson and daughters Rilla and Evelyn living in Lynn, Mass.

So curious to know the who, what, where, when, why and how they came to Heron Lake from New England then back to the East??

Any leads appreciated! Thanks
