I'm not sure that the following information refers to your line, but I'll bring it to your attention. Pages 756-57 of Samuel P. Bates's A Biographical History of Greene County, Pa. has an entry for Jacob Morris b. 1819 and the son of Robert and Salona Renner Morris. Jacob married Nancy Jewell and had ten children, including a son named Jacob J. At page 343 of Vol. 6 of Hennen's Cemetery Records of Greene County there is an entry in Macedonia Cemetery for Jacob Morris who died May 15, 1895 at age 75 years, four months and 28 days. There is a reference on the following page for Jacob's wife Nancy who died April 3, 1906 at age 81 years, six months and six days. In Vol. 2 of Hennen at page 96 there is a reference to the burial in Rosemont Cemetery of Jacob Jewell Morris who I assume was Jacob and Nancy's son. Jacob Jewell died March 16, 1930 at age 63. Also at page 96 is a reference to the burial in Rosemont of a Jacob E. Morris who died July 16, 1938 at age 56 years, four months and 22 days. Hope this is of help.
