I am looking for Mabel Beatrice Callan born 1887 in Beckton, West Ham. I have her in all censuses up to and including 1901. I cannot find her on the 1911 Census despite extensive trawling. Her mother Margaret, two brothers and two daughters are listed in Oriental Road, Slivertown, but there is no sign of her. She has a son the following year so I know she is alive in 1912. The son dies the following year in the West Ham Union infirmary. I cannot find a marriage or a death. I've looked a passenger lists but at present have not found anyone who fits the bill. Any other ideas anyone?
