I have all names in my line. I have Margaret Comb (1858 - 1931), daughter of James Comb and Esther Thomson. Her mother-in-law was Margaret Marr (born c.1836 - 1885), daughter of Robert Marr and Margaret Stewart.
My Andersons are from Whittinghame, I think. I haven't proven it yet but I think the father of my 3x great-grandmother is Robert Anderson (c. 1803 -), who married Agnes Brown. His children with Agnes were William, Robert, George, Marion and Gilbert Elliot.

Hopefully someone has a connection!
