Here’s some more I thought of:
St. Lorenzo Ruiz - the first Filipino martyr. He was a sacristan and a clerk who was trained by the Dominicans, and was a married husband and father. He was accused of homicide and to escape the legal consequences, he left the country with some Dominicans, but ended up in Japan where he and the priests he was traveling with were all martyred.
St. Benezet - a shepherd who, instructed by a vision, single-handedly built a bridge over the Rhone River at Avignon
St. Homobonus - a married merchant from Italy who donated a lot of his profit to the poor and is now the patron saint of business people
St. Prosper of Aquitaine - a lay theologian who helped propagate and defend the teachings of St. Augustine
St. Rocco - at age 20, when his parents died, he gave away all his worldly goods and spent the rest of his life as a mendicant pilgrim who tended sick people in the public hospitals
St. William of Rochester - a baker (or fisherman depending on source) who helped the poor and adopted an abandoned baby as his son; when the son grew up, the two of them went on a pilgrimage to Jerusalem and the son killed him on the way.
