Hi Linda, I am directly descended from (Rev.)George N. Marden's sister, Annie Kimball Marden.According to Ms Getchell's book, Geo. Marden (b.March 18,1836, married Sarah Hayford Oct.16,1862 in Bangor Maine)was a graduate of Bangor Theological Seminary. He held parishes in Maine and was Colorado College prof 1881-1905.
Annie and her husband, Charles A Ames (my gg grandparents) lived in Denver in about 1904, where my grandmother's brother (Willis)Marshall Ames was born. From there they all went to Southern California.
I'm afraid I don't know any more about George or his descendents, though.I'd love to hear more if you find new info!
