I consistently find that when adding a marriage, if a parent of the bride or groom isn't in my database, I can't add them via AS once I have added the bride and groom, as all the Edit>Add... items other than Unrelated Individual are greyed out/unavailable.
The help file states
, however, it is unclear where one should do this.If the individual or their parents are referred to in the marriage record but don't exist in your file then you should add them first using Add Parent, Add Spouse, Add Sibling, Add Child, or New Unrelated Individual.
I find I have to back out of the addition, go to FH, add the parent(s) that way and then come back to add the marriage again.
Am I missing something? It isn't the same on Birth/Baptism entry, where the Edit>Add Parent items are active.
