These varieties, like most citrus, do not need another variety to cross pollinate them. In fact a few varieties, like W. Murcott, people try to keep other varieties away from them so they will NOT cross pollinate and so will not have seeds. They will do fine on their own.

Hi, Thanks for replying. Some plants will pollinate themselves as the blossom closes and others you need to act like a bee and pollinate the bloom with a small brush. Will citrus pollinate themselves upon closing of the blossom? My plants are indoors, so I don't have insect pollinators.

well, you could use a small paint brush and hand pollinate. I am definitely not the expert on indoor, though. All mine are outside in the ground.
