The man with benign essential tremor (familial tremor) is 76 years old and depressed and full of anxiety. I would think it a good idea to try a mild tranquilizer first before saying he has PD as well. Caution: Older people often respond badly to tranquilizers and antidepressants and can become even more anxious and "nervous" so have to be careful with these drugs. Even the old bromide of trying a course of Sinemet to rule out or in PD can backfire in older depressed people so one needs to cautiously and slowly introduce Sinemet over a period of days. "They" say one needs three PD symptoms - for instance, tremor, rigidity and slowness - to earn a diagnosis of PD. I've seen depressed older persons without PD look like that.
