I was THRILLED to read your posting. My husband's ggg grandfather was Dr. Morris Bartow. I am researching his family, along with two of his first cousins.
John Brandt Jr.married Margaret Bartow, the daughter of Dr. Morris Bartow.She died in 1855, I believe and he subsequently remarried. They had three children: John Morris Brandt (my husband's line) b. 11 Feb 1849 Jennie Matilda b. 12 June 1851 (married George Knapp) Margaret Bartow Brandt b. 6 Oct 1854 (m. Millard Rapp)
I have a lot of BRANDT information but barely anything about Dr. Bartow. I would LOVE to have copies of the diploma and other information you have. Please contact me firstname.lastname@example.org
