Since that is the number of this post, I thought I'd post a link to a fine site about Culloden, the date of which was April 14, 1746.

I was actually trying to discover whether there was sufficient reason to be cautious about identifying with the Black Watch tartan when I came across this site.

I guess the truth is that nasty things were committed by many if not most of the clans.
