Which context were you reading???? I'd like to see it more explicitly.

Superficially, this sounds like a biology context than a geology context.
In this case, "yes, you can discount it."

If you were discussing geology-like context, you are describing
well-documented *ABSURDLY OBVIOUS GARBAGE*, which would give me further
concern for the standards in this field.

Yes, there are multiple-chains of radioactive nucleides that could be
used, but this doesn't fundamentally alter the method: the "daughter" is
the one that requires proton decay to decay.
