Raspberry planting

Bought one plant, and got a half-dozen starts from my folks' house, where they have a big, old patch of raspberries. I think they are fine-tasting. I don't know what variety they are. I expect the kids will eat them all. The are spreading all over the patch this year.
6/10/15: The berries are buried under a ton of new foliage. They are just starting to ripen.
7/8/15: I cut the foliage back last month. These have been ripening over the last few weeks and are almost done now. Purchased plant has elongated berries, and are very sweet. Plants from folks' have round berries and are not as sweet, although there is some variation. Some have more flavor than others.
