What is a sixth cousin?
Your sixth cousins share a 5× great-grandparent with you, seven generations back. Your 4× great-grandparents were siblings. Each of you stands seven generations below that shared couple, which sets the cousin degree at sixth with no generations 'removed'. Cousins this distant almost always surface through records research or DNA matches rather than family memory.
