Hi, Sarah Wycherley and Thomas Harrison are my great great grandparents.I have never been able to find a marriage between them either. I agree with you about John Buckley - he appears in every census as "married" but there is never any sign of a wife so I think they were probably still married. Sarah also had an illegitimate son in February 1861, Thomas Wycherley. He died in March 1861.Sarah and Thomas Harrison had two children, Walter and Joseph.Thomas died in 1893 and Sarah died in 1903. How are you related to Sarah?
