Tychon

The correct derivation should be the ancient Greek noun τύχη (tyche) meaning "fortune, chance" (see Tyche in the main database), especially when you consider that τυχῶν (tychon) is the genitive plural of that word. [noted -ed]

It looks like the derivation from τυγχάνω (tynchano) is more likely to apply if the name is spelled as Τυχόν, which is not the case here.

Perhaps it is better to compromise and mention both etymologies instead of just one, since both are feasible for this name.
