Regarding the middle name BONNER. You might consider, although it is a long shot, that the name was a misreading of the given name of Ostfriesian origin of BONNE. In my husband's research in Northern Germany, the part right next to Netherlands, the given name for boys in his family was sometimes BONNE. His adoptive father had such a name, when he came to the US it was interpreted as BONNIE which he didn't like much so he went by his middle name ARNOLD. Just a wild card. Sheila Santa Barbara CA
