Partial family trees (searchable) are available for the participants in the Y-DNA project. You may access the data here. The trees are limited to individuals born before 1870. If you are a descendant of one of these families, it means a male relative of yours has had a Y-DNA test and is in our project.
If you find errors, have newer information to contribute, would like to find out more about any of these specific families, or have information about other Bacharach families, please get in touch. Over time, we plan to post more partial trees in order to ask your help in connecting them to each other.
