What sort of information are you looking for, Jeff? The Book of Dow traces that family back to the immigrant to America, Henry Dow. At the time the book was published, 1929, the farm was a 400-acre nursery farm belonging to D. Webster Dow, father of Carl Plumer Dow.
The book gives Carl's m. to Kate Adams 8 Jul 1906, and lists only the first child, Katherine b. 29 Aug 1909.
It also mentions the homestead in the biographical material on the ancestors of D. Webster Dow.Some of the material in the book is taken from a bound manuscript of Gov. Samuel Plumer, who evidently had planned to write a history of Epping.
