Yes, he could, with proper paper work. There has to be a valid reason.
Both persons' first marriages must be annulled by Church, and then the couple must marry with a Catholic ceremony. If either of the first marriages are found valid by the Church and are not annulled, then the Catholic and divorced non-Catholic cannot validly marry in the eyes of the Church.
The civil marriage would not be recognized by the Catholic Church and the couple would need to have the marriage blessed by the Church.
Any marriage, which takes place in the Catholic Church, is valid. When one wishes to marry, one should contact his local priest; the priest will give instructions to the couple and the non-Catholic must agree to raise the children in the Catholic Faith. If the priest determines that the intentions of the couple are in union with Church teachings, he will permit the marriage. However, if one were to marry outside the Church...the Marriage is not valid.

Answer: The Catholic widow is free to marry. You are also free to marry in the Catholic Church. This is because your first marriage was not a Catholic one and, according to Church law, it should have been. It will be simple matter of speaking to your local pastor and filling out a form to be sent to the diocese.
