Just avoid it, by saying, 'was born to ....'. If you want that is. It isn't a huge issue.
Funny thing is though, this reminds me of a passage in Luke, where the Sadducees ask Jesus a question regarding the resurrection, which they didn't believe in. He said, the LORD said to Moses, that He is the Lord of Abraham, Isaac, and Jacob, for He is not a God of the dead, but of the living.
So, if it would be offensive to you, or someone who asks, to use 'was' instead of 'is'. Who cares, keep them happy. In the mean time, do what ever you are most comfortable with.
