The von Rosenberg Family website is an online resource for descendants of Peter Carl Johann von Rosenberg and others interested in the family’s history and activities. It complements the family’s Facebook page by bringing together information about the annual reunion, family news, and resources for members. Visitors can find current and past newsletters, business meeting minutes, a family tree, historical material, and a blog with the latest updates.

The site also invites relatives to request additions or corrections to the family tree, helping keep family records current. Reunion information is shared as it becomes available, with dates for the next gathering announced by the family. Through its General Store, the family offers books, shirts, and other items, with a price list available online.

Additional sections introduce family officers and historians, provide a gallery and sitemap, and offer contact information. Overall, the site serves as a central hub for preserving family history, sharing updates, coordinating reunions, and connecting members of the von Rosenberg family of Texas
