Natale is an adjacent form of the Latin word natalis which means 'birth or relating to birth'. I think that natale is sometimes literally translated in context as 'birthday'.
Siloam is Hebrew, but the only meaning that I have ever heard is 'sent' (and I can't confirm that definition). The Pool of Siloam is in Jerusalem and is supplied with water via a conduit carved through rock to the Gihon
Spring. The explanation of the name: pool of 'sent' water. In theory, it is the place that
Jesus healed the eyes of a blind man by applying mud to the eyes and directing the man to wash it off at/in the pool.
Or maybe you are thinking of
Salome?
