We are making a new series, which will follow people in their quest to find answers and, with the help of Ancestry, help them find family members they have never met or been estranged from.
Whether it's a family secret, divorce or distance that is to blame, we’d like to hear from you.
It could be a sibling, parent or child - we'd love to hear your story so get in touch!
