I apologise for coming rather abruptly as I assumed my changes would have to be approved rather than take affect straight away.
I have been researching Dinah in relation to my ancestors and here is her background from the sources on Ancestry and on the web.
She was born Dinah Nadyejda Mec (pronounced Mess).
Her father was Fernand Archer Mec, but he used the name Ginsburg after being adopted by an uncle (meaning she has three surnames plus married names!).
Her mother was Lisa Everth.
