Thomas Greenleaf Blakeman (1887-1953) was my grandfather. His grandfather was Birdseye Blakeman [1824-94]. Both show up all over the internet.
Oddly enough I can find no reference to Thomas Greenleaf Blakeman's father, nor Birdseye Blakeman's son, whom I assume would be one and the same, except that Birdseye Blakeman "... leaves a wife, one son and a daughter."
Birdseye's daughter, Marianna Blakeman, married a Mr. Lewis.
