I have come across a very interesting nickname in my uncle's Davenport line. "Toad" Every Elias Davenport went by "Toad" or "T.D." My uncle was a "late" baby, and only knew his father (Elias) by those names. "Toad" began with "The Owld (old)" or elder, much as we use "Senior" to denote an older person with the same name. It eventually morphed into "Toad" Sharon
