I have just found some of this info. My dad lost contact with his family and passed no info to me! His name was Harry LaHart. He died in 1980. Had Roseanna, Emma, Mabel, Clayton, Walter and Lottie that I know of LaHarts. All passed. Looking for any info, any at all. I have just connected with Dorothy LaMountian in Plattsburg, NY, daughter of Roseanna LaHart.
