Irenius Dow Stewart was my gr-gr-grandfather.I am "fishing" for his mother's family.She was Laura Mary Smith (b CT 1815, d 1852 IL).Her mother was Almira D. Smith (D for Dow? - b 1795 CT, d 1879 Providence RI).Almira was the widow of a "Capt. Smith, lost at sea," according to Irenius.I found Dr. Ulysses Dow in the R.O. Decker book "The Whaling City."Preponderance of the evidence suggests that Capt. Smith was Robert B. Smith, whaling captain (1794-1828), drowned in the Pacific.I JUST received copy of bio of U. Dow, by R. Wall, thru InterLibrary Loan- have not read any of it yet.
