Who was Maria Gertrudis Tules Barcelo in 1821 Santa Fe?

"Tules" was a Santa Fe saloon keeper and gambler with a notorious reputation who, during the Mexican American War in 1846 loaned the US Army stationed in Santa Fe enough cash to meet their payroll and prevent mass desertion. She was variously described in the American and European press as:

1. Old and toothless, very beautiful and black haired (or even as a redhead).

2. Mexican from Sonora, born in Taos (or even a Frenchwoman).

3. A devoted wife and mother, a madame and prostitute (or even the Governor's mistress).

4. All conceded that she was a brilliant gambler.
