Elsie and Ernest as toddlers it just doesn't sound right somehow!
My friend has twin grandsons,about 18 mths old called Ernie and Bertie

My mum was called Hilda,I have a friend called Edna,both names you never hear today.
Mind you no one calls a baby Carol now do they? Gladys and Ethel are also names you never hear.
My grandaughter has Lily as one of her middle names,named after her great grandma.
I had a grandad called Albert and a great grandad Herbert,and then there's Hubert too.
