My McConn* connections are distant, but centered in Washington, Mercer and Lawrence Co., PA connected to Alexander Thomson. This line also has some Smiths who do not connect to my ex-husband's Smiths that I know of. Another line settled in Jefferson Co., OH shortly after 1810 so I have researched in Jefferson Co. a lot, centering on Letitia Gray, a widow who settled there with her son Robert. My grandfather McKee's mother was a Thomson and he married Stella Gray in Jefferson Co. But thank you for asking.
