Thomas S. Renshaw (and Co.) had dealings in 1818 and 1828 in Georgetown, DC. He is working in Baltimore by 1801 and then between 1811 and 1815. He is master to George Taylor, who was born in Balto in 1796. He moves to Chillicothe, Ohio between 1816 and 1839, where he probably dies.

FWIW, his date of death can be narrowed down to between 8 Dec 1846 (will written) and 9 Oct 1849 (will submitted for probate).
