Early Origins of the Janssen family

The surname Janssen was first found in Northampton where they held a family seat as Lords of the Manor. The Saxon influence of English history diminished after the Battle of Hastings in 1066. The language of the courts was French for the next three centuries and the Norman ambience prevailed. But Saxon surnames survived and the family name was first referenced in the 13th century when they held estates in that shire.

A great wave of immigration to the New World was the result of the enormous political and religious disarray that struck England at that time. Families left for the New World in extremely large numbers. The long journey was the end of many immigrants and many more arrived sick and starving. Still, those who made it were rewarded with an opportunity far greater than they had known at home in England. These emigrant families went on to make significant contributions to these emerging colonies in which they settled. Some of the first North American settlers carried this name or one of its variants:
