When viewing a marriage there is an option to attach a record source. the only options are to add new, add from source box. Why cant I add from sources that are already attached to the individual?
Welcome to the "Community.FamilySearch" Forum.
I am just another 'lowly' User/Patron ...
Short Answer: BECAUSE the "Source" is ALREADY 'Attached" to an individual/person; hence, "Duplication".
IF, a "Source" is ALREADY 'Attached" to an individual/person in "Family Tree" of 'FamilySearch'; THEN, there is VERY Much the likelihood that there is a Possible "Duplicate" of the individual/person that you are TRYING to attach that "Source" to.
That "Stopper" is in place, to ENSURE, that one does DO some "Research"; and, investigate, whether or not, there is, in fact, a Possible "Duplicate"; where, one MAY be able to "Merge"/"Combine" them.
WHY attach a "Source" that is ALREADY 'Attached" to an individual/person in "Family Tree" of 'FamilySearch'?
That is the real question ...
One must do their 'due diligence', to make certain, that this is NO Possible "Duplicate", of an individual/person in "Family Tree" of 'FamilySearch", that one is "Attaching" a "Source" to.
IF, there is a Possible "Duplicate"; THEN, "Merge"/"Combine".
Simple really ...
Just my thoughts.
One additional issue with marriage or relationship sources is that they are not currently visible in the Family Tree app. Relationship Notes can be added & viewed in the Family Tree Mobile app.
