personally, I think if silver is someones father, it would be ultear.

-gray said he had seen deliora killing his parents -he is "nothing special", at least compared to ultear ->she was born with a dangerously high amount of magic -it seams to be fanon that this silver visited ulls (aka ultears mother, not grays) grave

beside, the theory fails at the point, where gray said the magic would be like ice shell. not only ull (who has hopefully no blood-relation to her man/boyfriend) but also leon were able to perform it. with other words, magics aren´t inherited
