Does the Wiccan religion claim a history connected to the first Christmas tree?

Answer 1

Not precisely.

What we do know, not as a claim but as fact, is that many of the customs and traditions now associated with Christmas were Pagan in origin and have been around for far longer than Christianity:

Answer 2

I believe that Yule log and Christmas trees, like the predecessor said, are rooted in pagan, not Christian, beliefs and practices. I'm sure that many Christians may not care for that knowledge.
