Jewelry marked Danecraft and the C imposed over an F would have been made prior to the buyout in 1945. James Felch started another jewelry company after he left Danecraft, but it only operated a few years. Jewelry from this company may have been marked Felch. Victor Primavera, Sr. died in 1977.
Gad is another ordinary common noun in Hebrew. It means 'good luck'. We all want as much of it as we can get. So it is not surprising that it became a proper noun, the name of some people, a tribe of Israel, and a god. The god Gad was not ordinarily identified with Baal.
Since the Hebrew word for hand is ×× (yad), the name Jedidiah resembles a meaning of Hand (in) Hand (with) The Lord. The author of Deuteronomy makes a playful reference both to the name Jedidiah and the similarity between the verb to love and hand-hand (or else, Nathan seems to refer to Deuteronomy).
