A slightly odd one for you!
A Lilian Squance allegedly married a chap called variously Len, Charles or Mac Crapp somewhere around the latter half of the 1920s. The various researchers I work with have been unable to find an actual wedding so we suspect none took place. However, we do know a child was born and we have the birth certificate which states the mother as Lilian Crapp and her maiden name as Squance. The child was born in Wales (Llandilofawr rural district) but the fathers occupation involved travelling (he drove a road roller and moved around the country).
I appreciate it is a bit vague, but this gentleman seems to have made a career out of being elusive and contradictory!
