I cannot find information about a Margaret Anderson who died in London in 2001 at the age of 80. Public records and readily available online databases do not contain a record matching this specific description. There are many people named Margaret Anderson, and without more identifying information (such as a middle name, profession, or other details), it's impossible to verify this death.
To help locate information about this individual, I would need additional details. This could include:
- Middle name or maiden name: Adding a middle name or maiden name significantly narrows the search.
- Profession or occupation: Knowing her profession can help pinpoint her in relevant obituaries or biographical resources.
- Address or neighborhood in London: Knowing the area where she lived would focus the search geographically.
- Family members' names: Information about her family (spouse, children, parents) could be valuable.
- Any other identifying details: Even small details, such as her hobbies or affiliations, could be helpful.
If you can provide additional information, I can attempt a more focused search using different online resources, including genealogy databases and newspaper archives. However, keep in mind that even with extra details, finding information about someone who died over 20 years ago can be challenging.
