Jacob Terrill - Possible Match

I'm going to quickly tag Lemuel Jacob Tirrell and Capt. Jacob Tirrell for discussion as possibly the same person.

I've been trying to find the Ancestry of Mehitable Cobb (also know as Hattie), who was born c1800 in Abington and died 2/25/1879 in Mansfield. Her father is listed as Jacob Terrill and mother as Experience Terrill.

The only Jacob Terrill I can find in the area was the one living closely in Weymouth. It appears he was born March 2, 1767 in Weymouth and died on November 15, 1841 in Bridgewater.

Based on online trees, this Jacob was the son of Benjamin Terrell and Hannah Terrell, and married Sarah Derby.

So not sure if Mehitabel was illegitimate or if I'm just looking at the wrong Jacob Terrill.
