My possible Dutch connection

I found out today that my ancestor's name was not Matilda Lemon, but Matilda Lehman. Lehman is apparently a Mennonite name, and this page makes it seem plausible that Matilda Lehman could have a Netherlands connection. Lehmans moved to Ohio, at one point, and the Beardsleys lived in Ohio at the right period. It was in an 1870 census where Solomon Beardsley said that his mother was born in "Holland". Matilda Lehman is said to have been born in 1812 and died in 1860.
