If you have British ancestors, you can see what events were going on that many have caused them to be draw to and flee from a place.
Since the British are the oldest enemy of the United States, I find it interesting what they say about Anglo-American events. Like in March 1765 there were riots in the American Colonies over a Stamp Tax. But I find nothing on the War of 1812 where Washington was burned, Baltimore and New Orleans attacked, savage Indians sent to kill all whites in Illinois, the burning of American settlements along the Great Lakes and other omissions. However British victories over the French are listed.
