1910 - John Coleman's cottage in Eltham circa 1910

This photo shows John Coleman's cottage which stood on the corner of Main St and Diamond Creek Road up towards Research. It is almost identical to Peter Carrucan's cottage which still stands at the corner of Bible St and Napoleon St in Eltham.
If we assume it is normally the eldest son who takes over the family farm, then it would have gone to John Patrick Coleman (born 1857). He and his wife Mary Agnes (nee McHugh) had 3 children - John Francis (born 1895), Agnes and Edward. Now there are 3 children in the photo and they are in the right chronological order. The size of the eldest boy might indicate an age of around 15 so that would put the photo at around 1910.
While this fits the context, it is very much speculation. If you have further information, please contact me...Tim
