Steve, thank your wife for caring about these two beauties.
I think the second one is a Piebald squirrel which is a rare genetic anomaly. It is an AWESOME anomaly.

I'm not sure the first one is a dwarf. Is it small? How long has this one been observed in the cemetery. Dwarf don't live long in nature. To help these two you could add calcium carbonate powder to your nut paste. That will help tremendously because the nuts aren't particularly healthy. The calcium carbonate will help. You could also try avocado. Most squirrels really like it. I'm not sure about a wild though.
Welcome to The Squirrel Board.
We would love to see more pics of these two.
