I have know idea who T. Sweeny's father was, it could be Arthur, but the only info I have is the info in my original post. Do you have anything on your Courtney connection?I have pretty much hit a dead end with them also.Lucinda Courtney's father was William Courtney b. 1824, his father was James Courtney b. abt. 1792.Lucinda & T. Sweeny lived in Rochester, NY according to family obit's, but Chicago, IL is also mention. Let me know if anything clicks.
