The birthplace strand is quite a mélange for the year 1102. May I suggest « Boulogne-sur-Mer, Picardie, France » arising from two historical factors:
1. "Pas-de Calais" is a départment designation. The original 83 departments were created on 4 March 1790, during the French Revolution, which includes Pas-de-Calais. https://en.wikipedia.org/wiki/Pas-de-Calais#History
2. "Nord-Pas-de-Calais" is a province designation that wasn't fully formed until ca. 1678. "Historical French provinces that preceded Nord-Pas-de-Calais are Artois, French Flanders, French Hainaut and (partially) Picardy." https://en.wikipedia.org/wiki/Nord-Pas-de-Calais
