The first Denbow or Denbo that I know of in America was John Denbo who arrived in Maryland around 1630 as an indentured servant from England. The first generations in the new world added and dropped the "w" depending on who wrote the document. My Denbow ancestors came to Ohio from Maryland in the 1820s and settled in Monroe County. If I can provide you with any more information please let me know. What branch of the family are you?
