I found this pretty cabinet card photo at the Will Rogers flea market here in Fort Worth, and unfortunately, I do not have any information at all about Miss Eunice, who her folks were, nor where she came from. The picture was too striking to pass up, though, and perhaps a Waddell family researcher will recognize her!
back is written,
"Eunice Waddell, coz.."
"Coz." most likely being an abbreviation for "cousin," though whose cousin, I do not know.
