The Jackson farm was lot 183 Talbot Road, Romney Township, Kent County, Ontario, Canada so the Jackson's and Baldwin's were neighbours. I found a marriage notice for Baldwin and Newham. From "Early Chatham Presbyterian Marriages 1848-1869" All that is recorded is--Baldwin, Sarah Jane age 19 of Romney, married Spencer Newham 1856 July 7. I don't know who Sara Jane is. Our Hannah was born circa 1858. Since John died in Canada in 1867 and Sara his wife was listed in the 1871 census, I don't understand how their daughter went to the U.S. and married. She must have gone with a relative or did she marry in Canada. Maybe she was with Sarah Jane and Spencer Newham. Will try to find out more.
