Now I have another question. One of the last Heathfields in Glamorgan that I can't account for is Winifred M Heathfield, born 1915 in Cardiff. The mother's maiden name is listed as Heathfield which I took as meaning that the mother was unmarried. However I've just traced a marriage to Samuel R Anning in Cardiff 1934 and the bride is entered twice - once as Winifred M Heathfield & once as Winifred M Hasell?
Likely to be another child of Emma's if not William's?
Cheers,
Mark
