Interesting; some of the names mentioned as funny, odd or strange do not sound so to me, and some not even that unusual.
From DH's side of the family, he great grandmother gave birth to eleven children. Except for two of them, they all shared a name (first or middle) with at least one of their siblings. The first two boys were Frederick Carl & Carl Frederick. Four of the boys had William in their name, There was a Henry & a Henrietta; they weren't the only girl & boy shared names, but I don't recall the others offhand. No twins to explain any of the repetition.
On my side there were Uncles named Ozro (nicknamed Bote), Leeman, Irvin, Watterson, Alfred, Oscar, Irving, Powell, Newton, San Francisco, Baylis, Bowlan, Dow, Amos, Loranzi Napoleon, Whitmore, Carroll, Sherwood, Joab. Aunts (pronounced Aint) Lucretia, Olive, Elvira, Balzoa & Balzora, Ensley, Luccie (not sure of pronunciation--several generations back--so it might have been an odd spelling of Lucy), Jamina & Jemima, Roena, Thoene, Cincinatti, Pearl, Elmer (pronounced as Almer), Ora. Lots of use of family names follow down the generations as middle & first names.
