aleathea

HI, I'm Derek Barraclough and live in West Yorks. Desperately seeking Aleathea Knapper. My grandmother, possibly from Wolstanton. She died in Normanton in 1946. She married Joseph Barraclough a coal miner in 1902 aged 21yrs. So she would have been born about 1881/2. I have not found her on the 1881 census. On her marriage certificate it gives her fathers name as Joseph Knapper, Miner. One of the witnesses is signed Emily Knapper. Any help would be very welcome as I keep finding dead ends. Thanks, Derek.
