Hi Colin. There is a Robert Richard Clarke in 1883 aged 19 born in Liverpool serving in the 18th Hussars I will search his Army records to see when he was discharged,If he stayed in the Army until the end of 1910 it could be an overseas marriage,my sister Joan has also found him (if it is the same person working on I think I.O.M. boats,she is looking further into this.Will let you know if we find anything. Do you have a death for Frances Marion, the only one I can find is for a Frances M in 1959 aged 72 in Winchester.
