Is it a coincidence that my great-grandfather had the name Florence McCarthy? Any relation? I know nothing about him other than that he married my great-grandmother, Jennie Hicks, and was a letter carrier in Cinncinnati, Ohio in 1890, the year my grandmother, Jennie McCarthy was born. Florence and Jennie had four daughters altogether: Jennie, Sue, Lauretta, and Margaret. Apparently, Florence was quite a drinker and a character. He carried a gun and was known to use it when he had too much to drink.
