My boys became fascinated with St. Martin of Tours last year when we read about him on the morning of his feast day and then went mass that day. As it turns out, Father Jeff (who said mass) had a particular interest in St. Martin and gave a fairly lengthy (for a weekday) homily. My boys were very excited to share information with Father after mass. This really made St. Martin stick with them. Plus, St. Martin really is a cool guy- you can wear a sword if you dress up as him on All Saint's Day (as my 7yo did)!
