Yes, Yes, Yes... Especially on some of these mystery manufacture hubs.
Another thing is the wheel set. After breaking multiple spokes on one set I checked the spokes. The whole wheel set was of of mystery manufacture. The spokes were around 15ga but less in diameter then 14ga. For me averaging about 240# I am sure they were stressed. My solution was to rub out a chamfer using a large drill bit by hand on the hubs as I replaced the spokes, one by one. The new spokes were 14ga Sapim. Fun, Fun, Fun...
This has been my favored source for spokes:

Further note: Having an extra wheel set is a real blessing. Think about it.
