Dear Ms. Fenster,
Thank you for posting your request on History Hub!
The National Archives and Records Administration (NARA) is the depository of the permanently valuable non-current records of the Federal Government. Since Glen Park is jointly administered by the Village of Williamsville and the Town of Amherst, we suggest that you contact them directly about primary records for the Glen Park area.
We hope this is helpful. Best of luck with your research!
