Not sure how I missed this until now but we have a (relatively) new blog here in Lewisville called LewisvillePhotos.com. Actually, calling it simply a blog does it a disservice since it's very well designed and features lots of photos by the site owner Deb Phillips. Deb has a long and rich family history here in Lewisville (her GrandPa bought the roller mill in the 1920s) and she provides a nice retrospective piece here. She also has historic photos of the Lewisville Roller Mill here. Good stuff.
