I also am the gggranddaughter of Peter and Marinda Morrison. I was unaware that they had a son named Alonzo. I have five sons for them; Peter T. (my ggrandfather), George, Dewitt, Elvardo, and Lorenzo. There is a Alonzo listed in the Daniel Brown household in the 1875, but I assume that he is Daniel and Marinda's son since he is only 4 years old, Peter was killed in the war in 1864, and Daniel and Marinda married in 1868. I would love to chat with you and compare notes. The possibility of Peter coming from France intrigues me. Thanks.
