Y comme "Yes !"

None of my ancestors is English, nor American. My only foreigners are from Switzerland and spoke german. But, sometimes, when I'm very happy to get something I wanted for a long time, I yell "Yes !". It can happen when I'm at the "Archives départementales", leafing through an old and dusty notary register. My eyes stop on a name that rings me a bell. This is the name of the fiancé ; I look for the second name, the bride's one... I know her too ! This a the marriage contract of a couple of ancestors I was looking for ! So, disturbing the peace and silence of the reading room, comes the "YES !".
