My grandmother was Myrtle Davenport Thierry of Detroit. I have a photograph of Henry Davenport -- her father, my great grandfather -- dressed as a tightrope walker. In family lore, we were told about Henry Davenport taking a small stove across the tightrope and frying an egg. Do you have additional information about the family? Sorry, I don't have more on the Davenport Street question.
