My mothers family is Knapper. Her Grand-father was David Knapper with his wife Marther nee Fairless.They had five children:Constance,Dorothy,Norman,Jack and Gladys. They originally came from England to New-Zealand.Year unknown,maybe early 30's.Every-thing was so secretive! Rumour has is that David was German or Polish but only speculation.So I dont know if we are connected. Wouls love to hear from you.
