I once saw this name on a baby name poll. The OP said it was the Scottish form of Thomas & means "twin". I did not find it here, though. I have seen it, w/ this meaning & background, and a few other sites, but they are all "baby name" sites, which I know are not the most reliable. I did a google search & saw sites for baby names & some that had random people w/ the name Tavish. Is there a reason it is not listed here? It has become one of my favorites. Does anyone know if the meaning I have found is correct? Is it even a "real" name? Any info is appreciated. I would also like to see it included on this site.
