Wires & lights in a box

Rebecca Ann (Bryan) Boone at Findagrave.

I think she had a Danish grandmother but most everybody else had been in the colonies for a generation or three. There is/was much confusion about the dates of Joseph Bryan Sr.'s two wives. Best guess for the mother is - Alice “Aylee” (Linville) Bryan. The Boone side was from Bradninch, Devon & the Morgans from Mold, Flintshire.

As for the song, pick your Garryowen thread but, typically c.1770-80 lyrics to the tune of Auld Bessie; the latter not much older by the current sources.

Later American: After Dibdin's Harlequin Amulet, Latour &c &c Gary Owen, the instrumental, was popular country dance for decades on. Someone like George A. Custer would have been hearing the music since his grade school cotillion.
