Excellent inputs, TY!
I'm guessing your pregnant onion was Albuca bracteata {formerly known as Ornithogalum caudatum}? I did a quick search and found other anecdotes of this giving people a rash, Fo' Sho'!!
FWIW, I'm not fair at all, quite the opposite, more Mediterranean. Until the past few years, none of the plants I mentioned gave me a rash except poison ivy. So glad I finally realized it was 'my old buddies' that had turned on me. Not that I'm happy about that, but I know how to stop getting itchy rashes.
