yes, Barry. my half-brother Don Lumbert (Lumbert-140 living) and my son (living) who is not a Lumbert but has my DNA. they were both tested at Ancestry. since they are both living, I don't know if you can see them but I have put my DNA match to my brother Don on my father's profile (Lumbert-134, deceased).
I have no idea yet how to use this on any generation past my father and I'm not even sure I worded the source reference correctly. I do see reference to my DNA match on successive generations, on the public profiles, so maybe my sourcing was sufficient.
