Alpharetta to debut film depicting its predecessor

“Saving Farm House,” a short documentary film about Alpharetta’s beginnings, is to have it debut screening in the city Thursday evening.

Presented by Alpharetta and the Alpharetta & Old Milton County Historical Society, the showing is free and is to start at 6 p.m. in the Community Room of City Hall, 2 Park Plaza. Information:

The film depicts the settlement of Farm House in the 1830s; it had a post office, grist mill, sawmill and cotton gin along present-day Ga. 400 and Old Milton Parkway, according to a city announcement. The town operated into the early 20th century.

“It’s our community’s starting point, and not many communities can save their original settlement,” said Alpharetta Council Member and Mayor Pro Tem Donald Mitchell. “We hope to make this into a historic park for the community.”

The screening will be followed by a question-and-answer session with the film’s directors and local historians and, at 7 p.m., the monthly program of the Historical Society.

Kathi Cook, Alpharetta community development director, and Morgan Rodgers, recreation, parks and cultural services director, will talk about “The Future History of Alpharetta.”
