Hullo Meg, There are currently 3 persons wih the name Halcro in the public telephone listing for Edinburgh. None of them is resident in or near Tipperlinn Road. There are also several Halcrows in the directory. Tipperlinn road is in a quiet residential area (Morningside) on the southside of Edinburgh. It is near George Watson's College and The Royal Edinburgh Hospital. You should be able to find it on an online map. You mentioned that "Certainly he was involved in some kind of community or church activity". I suggest that you give some details of that as it might be helpful in getting closer to what you want to find. Eunice Smith Edinburgh, Scotland
