Hi Mathilda
Welcome to Rootschat, even though you've been a member for a good while

A bit puzzled by Glassenlen as I don't see it listed. Would it be Glasserton, the parish? I did a quick check on the name but don't see any baptisms listed for him on the usual sites so...,
Do you have their children in date order, as it's sometimes possible to wok out parents names from the names given to children - for e.g. Husband's father's name is given to first born son, and wife's father to the second son. The opposite applies with female offspring.
