How to input adoptive-biological parents?

Do you have a young adopted child but know the biological family? Has one of your relatives been taken in by a family that is not the biological family? Do you have a same-sex couple in your family tree and want to include the biological parent(s) of their child as well?

Since Heredis 2026, it has been possible to enter multiple sets of parents.
See the article Add several sets of parents, which explains this feature.
