As part of the Integrator's project, I've sourced and created profiles for John Charles Foster (b. Ireland ca 1810), his wife, Rose Ann McClellan (b. Ireland ca 1812), and their daughter, Sarah (Foster) Schrier, and her family. The Fosters emigrated from Ireland and settled in Lambton, Canada in the mid-1840s, and then went on to Sanilac County, Michigan. Please consider adopting these profiles, and creating profiles for their other children, if they are in your family line.
