Hi.  Sorry it's taken me so long to reply, but I have access problems.
At the Block family house in Washington, Arkansas, we dug a trash
deposit dating early 1840s that included some fish including suckers and
catfish.  Not a whole lot of fish, to be sure.  The species list and
other details were published in Historical Archy in 1989 in an article
by Barbara Ruff and I.  The title is "A Good Man in Israel...", and was
looking mostly at faunal material and ethnicity, e.g., catfish are
definitely not Kosher but the Blocks definitely were Jews.  I don't have
a detailed reference to the article here at home with me, and I fear
that if I wait til I get to the office to reply, it might be another 2
weeks before I can get into email again.  Good luck.
