I don't have an answer to your question about who E.L. Robinson was but I'll certainly check my database of Robinson names. My Grandfather couldn't have been the E.L. Robinson who wrote the letters because he was born in 1868 but I wonder if he was related to the author of the letters - if for no other reason than the Robinson / Welden names. I'm writing because my Grandfather's name was Emmet Robinson and he had a sister named Emma that married a Ralph Weldon or Welden abt. 1877. Emma Robinson Welden's son Wallace Weldon was mentioned in my Great Grandmother's (Julia Ann Thompson Robinson's) Pennsylvania will in 1931. Do any of these names show up in your research? Your response will certainly be appreciated. Thank You.
