So far, we only have one recording by J. A. Hultman in the database, and on that one, as on all other HMV recordings by him, he is identified as "Pastor J. A. Hultman." I'd leave it as is and then link "Pastor J. A. Hultman" and "J. A. Hultman" or "Johannes Alfred Hultman" as needed when they are entered.
