This is a working project, and much of what it still needs will come from other people: a record in a county archive, a will no one has pulled, a cousin who tests. If you have something to add, a question, or a correction, write. Every message is read.
For any man carrying Tyndall, Tindall, Tindal, Tyndale, Tindale, Tinlin or Tinning, or descending from one in the male line, who has tested or is thinking about it.
If something on the Line is wrong, or you hold a document that bears on it, a charter, a will, a parish entry, a deed, send it with the reference and it will be checked and credited.
Family connections, questions about the arms or the research, archivists and historians working on the same ground, and anyone who simply wants to say hello.
Documents and results shared with the project are used to test the Line, and are cited by archive and reference, not by sender, unless you ask to be named.
DNA results are discussed only at the level of the branch. Nothing identifying you is published without your say-so, and the raw data never leaves your own account.
