Certain profiles do have a memory section, but it cuts off somewhen between my 2-greats-grandfather's time and my 3-greats-grandfather's time.
Memory added for an example (it's a true memory, so it belongs there) -- https://www.wikitree.com/wiki/Perman-47
2-greats-grandfather was born in 1835, died 1874. He has a memory box. His father was born 1803, died 1852. He does NOT have a memory box. ?-greats died 1847 does not have a memory box.
Memories should be merged. It's possible that there was some bug today related to this morning's changes. If you email Jamie with the IDs of the merged profiles she can investigate.
