Was St. Valentine a Catholic saint?

One clarification. There is no such thing as the Roman Catholic Church. There is only the Catholic Church. The Word 'Roman' was added as a someone derisive description by members of the Church of England when they separated from the Catholic Church.

The number of recognized saints is hard to determine as there is no concise list. There are a number of saints that are not recognized by the universal Church but only in certain dioceses. They are local saints who were declared as saints before Rome took the responsibility of declaring saints in the 12th century and were never formally canonized or recognized as saints. If all these saints are included the number is estimated at 10,000 to 20,000 total.
