Looking for any information on the parents of Martha A. NELSON who married Sylvester Larned LANGDON on September 1, 1851 in Detroit, Wayne County, Michigan. They remained there for a few years, their first son William LANGDON was born in 1852. It is believed they moved to Iowa before 1855 although later Sylvester appears to have returned to the Detroit area.
Any and all help appreciated. Thank you in advance for your time and trouble.
