Thanks Kite
That makes sense
We never knew who Mr Platt was.... Clarence Thomas Platt married Caroline Dowsett in 1918 about a month before HW Wicks married her. As we could never find Clarence, I had decided that he was actually HW Wicks, and there was some insurance scam involved.
Now it seems as though maybe Clarence did exist.
It's all very complicated
Having had a break from doing my tree for a while, I now feel motivated to resume it, and will try to put a Clarence Thomas Platt query together for the advice of all you experts
