As Jonathan Batkin has well documented, there were several outstanding potters at San Ildefonso during the 1890s whose work can fairly accurately be associated with their names. Following publication of Batkin's studies, it has become easier today to identify late 19th and early 20th century pottery to artists with some degree of accuracy, or so we hope. One husband and wife team, who were extraordinary artisans, was Martina Vigil and Florentino Montoya.

Martina and Florentino have been praised as among the finest artisans at San Ildefonso. Batkin has illustrated a couple of their works in his book Pottery of the Pueblos of New Mexico 1700-1940.
