My Maternal Great Grandfather was a Stewart, became a Presbyterian circuit rider/Preacher in South Australia in 1800's
My Paternal Great Grandfather was a Welsh Harris; Came to Oz also 1800's.
The 'Harris/Harry/Perry' (Welsh) Tartan looks a bit like a poor man's faded Royal Stewart, which I don't care for, and is hard to get, so compromised with Stewart Black. (Executive decision here!)
Also have Black Watch (Universal they say) and for fun, and because I look cute in it - Irish Saffron. No (official) Irish blood, but I love the Irish!
The Clergy tartan is way too wimpy looking for this guy!
