This information may or may not be of help, but it doesn't hurt to pass it along:
My 2nd Great Grandmother Sarah Jane McHarg - m.s. Dunlop (b.1846 Newtonards, Down, Ireland) married William Peden (b. 1842 Newtonards) 29 October, 1864. They had 3 children: Hugh (1865), Margaret Jane (1866) and Mary (1869). William died 20 June, 1868 in Newtonards.
I have a name of James Peden as father of William.
Sarah Jane remarried in 1872 - I have more information regarding her genealogy if you need it.
Good luck in your research
Jim
