I am trying to find out my connection to the Sims family of Maryland.My GGGG Grandfather was Captain Kendall Sims Cropper.He was born in Maryland in 1781 to Edmund Cropper (b 1756) and Margaret Porter(born 1762). The custom seems to be that a family surname is used for a middle name, so I would very much like to find out the Sim connection. Perhaps it was Margaret Porter Cropper's mother's maiden name? Grateful for any info or insights. Thanks, Roberta Cropper Dell.
