Based on the provided locations, some key differences between the Luster and Rogers family lines are:
Geographic Distribution:
The Luster line seems more concentrated in the United Kingdom (especially Scotland and northern England), the Netherlands, Belgium, and parts of the northeastern United States like New Jersey, Connecticut and New York.
The Rogers line has a wider geographic spread across the United Kingdom, continental Europe (Netherlands, France, Germany, Switzerland, Hungary), the northeastern US, but also other parts of the US like Massachusetts, Maine, Virginia, South Carolina, as well as some locations in Canada.
Specific Locations:
Many Luster locations are in and around Glasgow, Scotland as well as other parts of Scotland like Paisley, Lanark, Aberdeen.
Rogers has a stronger presence in places like Nottinghamshire, Warwickshire, Gloucestershire in England as well as counties like Devon, Suffolk, Essex.
In the US, Luster seems more New Jersey/NYC area focused while Rogers is more widespread in New England as well as places like New Jersey, Virginia, South Carolina.
Rogers also has branches traced to continental European locations like the Netherlands, France, Germany, Switzerland that are not evident for Luster.
So in summary, while both lines have a British Isles core, Luster appears more concentrated in Scotland/north England and the American northeast, while Rogers has a wider geographic distribution across England, the US, and continental Europe. But there is still overlap in certain areas like London, the Netherlands, New Jersey, Connecticut etc.
