Regarding WikiTree's indicators,
We have the option to indicate that a father or mother is non-biological or uncertain.
Parents-Married: Default, connect them
Parents - Unmarried Common Law: No agreement here: Connect them and explain not married in Bio. or Do not connect them and indicate in Bio.
Parents - Unmarried Dalliance: Do not connect, indicate in Bio.
Father/Mother: Non-Biological: Do not connect and indicate non-Biological, explain in Bio.
From a WikiTree technology perspective, we default that a father or mother is biological and need to indicate if not biological so that the DNA matching can perform correctly. The do not need to be connected as partners.
From a Genealogical perspective we connect them so that they show up as married husband and wife, defaulted.
The rub then, is defining when to connect. If common law marriage is on the rise, then should not these folks be connected? Is the point of connection to show a legal marriage or a relationship? From a genealogical point of view, we like to see all relationships resulting in either biological issue or some kind of significant relationship. Adoptive parents being a corollary, with the non-biological indicator being created to accommodate this.
Yet we do not want to see every "one-night-stand" a person engaged in.
So do we need to better define the purpose and use of connecting two individuals? Is it ok to connect a gay couple for example?
I see the unmarried question has been asked several times, indicating reoccurring confusion.
I believe WikiTree’s policy is to connect married biological parents only but allow connection to a non-biological parent in certain circumstances.
