Two Tuberous Begonias

I’m so happy these two wonderful begonias have been with me already for many years and hope that they still will for many more years to come.
Unfortunately I don’t remember the names of them. The one with the double flowers is one I bought myself. The other one my husband’s cousin gave me. I surfed the web to see if I could figure out their names. The double one I couldn’t find but the other one I think is a Begonia Bertinii. It’s a bit embarrassing but I have to ask my husband’s cousin one more time for the name and then write it down and put it somewhere safe.
