I have "lost" my family between the 1901 and 1911 census. The Bureau family of Charles A, his wife Margaret (nee Griffiths) and children, including Charles Jnr, Tommy, Beatrice, William, Benjamin (and more) are all included in the 1901 census. I think their address was Cardiff Road, Aberdare. Charles Snr died c1904 and it seems Margaret remarried in c1910 but I don't know to whom. Perhaps the children took the step-father's name? Can anyone help with Margaret's marriage details which may help me trace the rest of the family, or advise where the family was in 1911?
