Four of my late Mums neighbours were named Betsy,and that was in the 1940 war era ha ha.. Best go for Doris, as that was my late Mums name. ha ha, There was also an Ellie in our street in the 1940 era,but her proper name was Ellen.
I had a friend,who wanted to name her daughter Tania, but she spent ages trying to decide if it should be Tania, Tanya,or even Tanniya. omg, such problems ha ha.
