Have your floral designer label all the boutonnieres and corsages with the first name and designation of each recipient.
Assign a helper (someone who knows the members of your family) to distribute the boutonnieres and corsages. Your florist will not know Uncle Harry and Grandma Josie. but your helper will know these VIPs and can point the florist in the right direction.
A little for-thought will help eliminate confusion when the personal flowers for your wedding are delivered.
