Bea, check out the data base. My photos are in both entries for Paris and Pink Nymph. Paris is a single. If it is a pink as the photo indicates it could be Pink Nymph. The only Merlot that I know about is a single. Perhaps there is a double Merlot that I haven't seen. There are several red doubles, such as Red Nymph, Cherry Nymph, Malaga, Amarantia, Double King, or Red Peacock. Those are just the ones that I have. So that one will be tougher to ID. Marking the pots is a good Idea to keep track of IDs. If you are using sharpies or a paint pen, you probably need to refresh the markings 2 or 3 times a year.
