Hello Cathy I am afraid I do not have any more information concerning Robert Delabertauche. I intend to visit Westminster Central Archives ,when I get time, since I believe they hold the parish records of St.Annes, Soho. My father is also interested in any information concerning his mother's family. I don't think there was much contact between Mable and her siblings,my father does notremember any aunts or uncles, although he does remember visiting a relative in Spitalfields. I would be very interested to see the family history that you mention and would appreciate any advice on how this can be obtained. Many Thanks.
