When I run the Printer Friendly view under Tree Apps for Seaberg-61, the parents of his paternal great-great-grandmother Anna Pehrsdotter (Pehrsdotter-2084, Mar 02, 1787 - Nov 19, 1835) don't load in. They are the same people as the parents of his maternal great-great-grandfather Erik Pehrsson (Pehrsson-2091, Aug 03, 1794 - Jul 12, 1859) and were added as Anna's parents first, but now only show up as Erik's parents even though they ARE still connected to Anna also. I waited a while after noticing this to see if the weekly update would fix it but it does not appear to have done so.
