The population was 72,891 at the 2020 census. In 1812, Elias Glenn, a district attorney, established a county seat near what is currently known as Brooklyn Park. He named his property "Glennsburne". The name was changed to "Glennsbourne Farm", and eventually "Glenburnie", as the property was passed through Glenn's descendants. Records also show the name as "Tracey's Station" and "Myrtle", after local postmaster Samuel Sewell Tracey and one of Tracey's boarders, before the final decision was made.
