St. Botulph, after whom the name Boston is ultimately derived (ie, from "Bo[tolph]sto[w]n"), was an Anglo-Saxon Saint who founded the monastery at Ikanhoe in 654. There is some debate over just where exactly that was, but the best candidate is the little village of Iken. This website has lots of information about Iken and St. Botulph and the effect he had and has there:
His feast was/is celebrated locally in England on June 17th (the date he died in 680) and Scotland on June 25th.
The Proper Lessons for Matins on his feast day are mostly extant in one manuscript, and seem to be drawn mainly from a vita that is known, complete, in other sources:
He is recognized as a Saint and was on the traditional calendar for the (post-restoration) British Catholic dioceses of Brentwood and Northampton, as you will find if you check the back of a Baronius hand-missal, though he is simply assigned the Mass Os Justi for an abbot.
He is not, however, in the traditional Roman Martyrology (though eight separate Sts. Valentine are listed, including two on February 14th alone); a little reminder perhaps of the victims of cultural (or liturgical) imperialism, about what is lost when one locality's meta-narrative attempts to devour those of others, to globalize tradition that is inherently local.
On that note, we might also do well to pray to St. Udalric of Augsburg, the first Saint from outside the Roman province canonized by a Pope, and to St. Walter of Pontoise, the last Saint in the West canonized by a bishop other than the Pope (who jealously hoarded that prerogative for himself alone in 1170). A tragic event we have perhaps never recovered from; in the First Millennium, there were over 10,000 Saints. In the Second...there were less than a thousand. Here's hoping the Third is more like the First!
