Hey Jim -
Add a Du to the Trueaux plus an i and you have the Walloon surname my antecedents carried for 110 yrs, there in that former Dutch colony till the F&I.
Comes out? I'm still hoping and expecting for your support and help as we try to put this trans-continental organ measuring contest together and to bed...
( See Jim's wiki link to Old Blenhiem )
Knowledgeable people on both coasts measuring both bridges on the same day -
An end to the my bridge is better cuz it eats kennel-ration, and endless editing of the wiki entry.
A fun and funky reason for some of us to meet up, and verify each others findings through pop-culture and the wonders of online video and social media ????
Too geeky?
