An Irish-American in Paris

I am American and have worked in Paris for several years in real estate. I just started working at a new agency and was assigned certain neighborhoods to work on. I recently came into contact with a very good client,"Mrs. Cooper", a French woman who was married to an American, and had already sold property with our agency before I arrived. She now had another fabulous apartment to sell, an inheritance, that happened to be on one of my assigned streets. Before going to meet her for the estimation, I dug up her old file from the sale of her first apartment : property titles, etc. I discovered that her father was American - and that her maiden name was the same as my own (a good Irish last name--I have absolutely no French heritage)! We were also from the same region of the US, she was born in the same city as my mother, and currently lived within 2h of my father's family in the south of the US. We had a surprising number of things in common....strange for a big city, in a foreign country, where I have a very finite area in which to sell property, that my first client could be a distant cousin!
