Our posters can only be generated from one Ancestry tree, so if you are wanting to make a combination poster you will have to make sure you have a tree in ancestry that has both spouse's family history information. If you do not have a tree that contains both side's information, you will either have to enter the information into one tree in Ancestry or you will have to manually add all of the photos and information onto the blank side of the poster.
