Joseph Harrison married Elizabeth Ashcroft, daughter of Thomas and Susannah (Elliott) Ashcroft. Children - *Thomas, Joseph, John, Elizabeth, Robert.

*Thomas Harrison (1734-1801), merchant/shipowner; lived at Crooked Intention; married Mary Porter. They had nine children - Joseph, Jonathan, Thomas, Daniel, John, Samuel, Elizabeth, **Mary, Ann.

**Mary Harrison (1767-1822) married her second cousin Joseph Harrison (1761-1815); five children: Jeremiah T., Eliza or Elizabeth, ***Mary Ann, Susan, Thomas Solomon.
Joseph and Mary (Harrison) Harrison built on part of Haphazard, 1805, and are buried there.

***Mary Ann, called Ann, Harrison (1802-1884) married John Graham (1778-1837) 1 Jan 1822. She was his second, possibly third, wife. Their daughter Ellen Jane Graham (1825-1870) married Francis Asbury Wrightson (1812-1898) 31 Aug 1848. This is our line.

Ellen Jane's sister Susannah Graham (1830-1912) married Edward Harrison (1825-1913) 24 Dec 1849. I don't know how Edward fits into the Talbot County Robert Harrison family, or if in fact he does. Would appreciate any info on him. They had a son Edward Graham Harrison who married Eleanor ?
(possibly Worthman).

I have no information on the descendants of the other children of Joseph & Elizabeth (Ashcroft) Harrison.

Hope this helps a little.
