Find Ancestors

Am helping a friend trace her Jewish Prussian roots. Between 1841 and 1861, the majority seemed to live in the London area. However, her ancestors, seem to have settled in Sunderland/Northumberland and I was wondering if anyone has a theory as to why?

Jews started to arrive in significant numbers in the north-east of England during the second half of the nineteenth century. The ports of the area, Newcastle, Hartlepool, Hull and Sunderland were the destination ports of many of the boats that plied the trading routes from the Baltic Sea. Most Jews moved on to the large cities of Britain, or overland to Liverpool and Southampton before starting their onward journeys to the New World. Futhermore, Sunderland had become a major port exported coal to the eastern Baltic, but there was little return trade, and some ships accepted Polish Jews, especially from Kretinga (Krottingen) in Russian-Lithuania, rather than lose money by returning empty in ballast. Many of these closely related immigrants came to improve their economic prospects and to escape the mandatory enlistment into the Czarist army.
