Irene,
Edith E. Scattergood married John Cadman in 1937 and they lived at 102 Couchman Road. Seven children with the surname CADMAN and mother's Maiden name of SCATTERGOOD were born in Birmingham between 1938 and 1948 - Margaret E., Pauline M., John M., Brian P., Keith W., David H., and Malcolm J. However, there is no matching birth for a Susan with a mother's maiden name of SCATTERGOOD. I have already stated in post #12 that there is no suitable death registered either.
That makes it almost impossible to track the last resting place of Susan. Cemetery records are in the Library of Birmingham, but we don't even have an accurate year. But I can tell you that she is NOT buried at Handsworth, Key Hill, Warstone Lane. or Witton. The other Birmingham cemeteries are not available online. So you can't get a death certificate to find out where she died. Possibly one of the children mentioned in my first paragraph are still alive, and might know more, but I am not going down that route on open forum for privacy reasons.
