Hi Thelma,
Apologies for my own slow reply but have been away for 3 weeks and just got back today.
I would be so pleased if you could find Wyndham Villa and take a pic for me. The head of the family was quite an eminent surgeon, so I imagine it should have been quite a large house. I've looked back through the census records to see what the other houses in the road were called, as it may help to find it. In 1901 in Connaught Place were (in this order): Glenare, Lahore Villa, Cardigan Villa, Elmgrove, Wyndham Villa, Penrhos House, Eglington Villa.
Many thanks, Barbara
