Well, J.J., I have found the marriage for Taylor/Drummond and the birth registration for four children. Isobel would be the oldest child and is the only one living relatives remember. She would have been born between 1910 and maybe 1916 ish. I think perhaps her record is not yet posted online.
The map site is excellent. I haven't found a relative yet, but the maps are just what I was looking for.
Many thanks, Linda
