If you have access to Connecticut marriage records, could you check for records of any of these marriages?
Charles F. Johnson b. 16 January ~1843 Connecticut d. 28 February 1913
m. Harriet Thompson (divorced ~1868)
m. Phebe Ann "Annie" Bryan in April 1892 (date given in military records anyway, but no record provided to confirm)
m. Georgianna (appears as his wife and next of kin in military records of his death in 1913 so presumably before 1913 and after 1892)
I'm especially interested in whether or not Charles F. Johnson listed the name of his parents in any of these records, but additional details of the women also greatly appreciated. If you can include citations and, if possible, images, that would be amazing! Thank you so much!
