I sent you an e-mail when I discovered your message. I never heard anyone in our family call Elizabeth---Betty. My Elizabeth and Mr. Kerwick had four children, Margaret(born? ) Ellen (born?) Mary, born 1855, and Simon born 1857. My dates could be slightly off. Margaret married a Gentry. Ellen married an Altar. Mary married a Houlihan. Hope to hear from you soon so we can unravel this mystery.
