Uriah Sumner is said to be the first settler in the town of Franklin.  It appears that he may have first set up a forge at McLenathan Falls and later started a second forge and mill in Bloomingdale on the brook which bears his name.  Sources are conflicting, however.

Malone palladium, May 10, 1900

"About the time of the first settlement at McLenathan Falls, [c. 1827] a forge was erected by Uriah Sumner on township No. 9 of the old military tract. This enterprise was also abandoned." See Franklin for the full article.  But see also this link
