Kathie, I have found two Morgans married to Doolens in my files and one married to a Morstatter who is connected with the Doolens of Marion County, IL.
J. Barr Morgan married Martha Doolen (b. 13 Aug 1837; d. 13 Jul 1900, daughter of Daniel Doolen, Jr.) on 23 Feb 1854. They had 12 children (by my count): Sarah, Elizabeth, Agnes, George, Antoinette, Susan, Daniel, John Barr, William, Gilbert, Walter, and Lemon.
Wesley Harmon Morgan, Sr. married Cora Etta Doolen on 2 Dec 1886.They had one child , Martha, that I have listed.I have Cora Etta listed as the daughter of W. Edward Doolen.
Isaac Alexander Morgan, son of Isaac Morgan, married Lovilla Eleanor Morstatter on 8 Aug 1944.
I have no information on the ancestors of any of the above mentioned Morgans but would appreciate it if you could fill me in or correct any errors.
