Hi,
I've been looking at the NSW Online (Internet) BDM index, for the above families.
I have found:
William Johnston married Margaret Cherry (7476/1894 JOHNSON WILLIAM CHERRY MARGARET WOLLONGONG), but cannot locate birth details for either and details of parents of William.
Margaret Cherry's parents are Martin Cherry and Mary Burns (Barns, Byrnes) (V1851549 97/1851 CHERRY MARTIN BARNS MARY LQ) Roman Catholic Illawarra, Wollongong. Again I cannot locate any birth details of the parents.
Any help would be great
Cameron
