Individual Details

Married Dr. Jacob Frye on 6 Mar 1812. She is said to have died on 15 Apr 1812 in Marion Co MO. This seems improbable and indeed probably should have read that she died in April of 1852, see later.

Found the following marriage record in Marion Co MO: Pauline Fry married Alfred A. Sterman on 22 Mar 1838 - no doubt the above children were Rebecca's grandchildren.
There was also a marriage from Elizabeth Frye to Samuel Ramsey on 17 Oct 1837 that could be another daughter of Dr. Jacob & Rebecca.

From the Whig published in Palmyra, Marion Co MO, dated 15 Apr 1852.
Died in this county on Monday last, Mrs. Rebecca Fry, widow of the late Dr. Jacob Fry at a very advanced age. (she was 58)

I believe that a daughter of Dr. Jacob and Rebecca married William Haydon, son of Thomas Haydon and Mary Kellar. They would have been first cousins. They apparently had no children and they both died quite young. William left a will dated 12 Oct 1841 that was probated in both Marion Co MO and Schuyler Co IL and he left a bequest of $150 to his mother-in-law Rebecca Fry, as well as a bequests to an orphaned nephew and some of his siblings.
