The most common cause of spoke breakage, by far, is fatigue. The most common cause of spoke fatigue is poor build quality. Once spokes start breaking, they continue to do so because of fatigue. Replacing them one by one doesn't fix the problem. Replacing them all at once does. What condition is the rim in? What condition is the hub in? Generally, it's less expensive to replace a wheel than to build one, but with your hub being rare, rebuilding might be the best plan.
