The last time I was at Haddington KH would be in the late 1970's, gave part of a Public Talk. Not this KH however though I cannot remember much more about it. We had lunch with a family afterwards, there were several witness families in the row of terraced houses, they were known locally as "Armageddon Row".
I knew a family who moved there many years later.
Did Paul Gilles come from there?
