Jacob Harman (Hermann) lived in Lower Saucon Township, Bucks County, Pa. He died in 1741. The name of his wife is not known, but she was probably the sister of Jacob Freley of Nockamixon Township, Bucks County, who administered the estate and acted as guardian of the children of Jacob Harman of Lower Saucon. From the various petitions of Jacob Freley to the Orphans Court the following facts appear: he was the uncle of Jacob Harman's children, Mary, Jacob, Elizabth, and Mathias; Mary was born about 1734, Jacob about 1735, and the other two children were younger; Jacob Harman had died in 1741.
Mathias, the younger son of Jacob, deceased, was evidently taken as a boy to Nockamixon, Bucks County, by his uncle and guardian, Jacob Freley. In 1775 we find him a member of Nockamixon Company, Bucks County. In the Pennsulvania Archives, 5th series, Vol. V., pp. 393-394, appear the "resolutions" of this Nockamixon Company, of which Mathias Harman was one of the signers. Other Revolutionary service for Mathias Harman is indicated in Pennsylvania Archives, Series V., Vol V., p. 358, where he is given as a member of Capt. Patterson's Company in Tinicum Township, Bucks County, Pa., May 22, 1780; and also in Pa. Arch., Ser. V., Vol. V., p. 418, where he is given as belonging to Capt. William Erwin's Company of Tinicum Township, Bucks County, Oct. 1, 1781..
In 1779 "Mathias Harman, Yoeman," bought land in Tinicum Township, Bucks County, where he lived during the latter part of the Revolutionary War. Oct. 28, 1783, he and his wife Elizabeth conveyed his home and farm to Peter Long. The deed was signed in German. Mathias Harman then removed his family to Frederick County, Virginia, where he lived until his death in 1812.
