Harold Iball m. Winifred Esther Withers, Sep Qtr 1919, Tenby. The only birth in right time-period is Sep Qtr 1893, Holywell, Flintshire. I can't find him or parents in 1901 Wales census. I suspect that he was stationed in Pembroke at some point during WW1, possibly Royal Welsh Fusiliers, and that would be how he met my great aunt Winnie.
I am wondering what became of them.
