Mein Stammbaum is a German-language family history website focused on the Heinemann family in Hessen. Built with webtrees, it provides an online space for exploring genealogical records and relationships through an interactive family tree. Visitors can browse ancestors and descendants, view compact and fan charts, pedigree maps, timelines, lifespans, and relationship information, or consult family and individual pages.

The site also organizes information into lists of branches, families, individuals, and media objects, with shared notes and a calendar for browsing dates and events. Search tools include general, phonetic, and advanced options, helping users find people and family connections. Genealogical reports cover topics such as births, marriages, burials, deaths, ancestors, descendants, and vital records.

The site offers multiple language options and includes sign-in and account-request features. Its content is presented as a family tree rather than a commercial genealogy service; the available page lists no news articles. Users can also access favorites and a default chart or individual view while researching the family’s history
