Dorothy E Duckworth daughter of Conrad & Pearl

Looking for any information on a Dorothy E Duckworth born to Conrad Duckworth and Pearl Shaw.Would anyone know when and where she was born.There was a Dorothy E Duckworth who married a Malcolm and had two sons in Cumberland, MD. I don't know the given name of this Malcolm and not even sure if this is the same Dorothy, but, the only one I can find in early census records for the same age group. She would have been born sometime between 1915 and 1921.Welcome any possible solutions.
