I have been more or less faithfully replicating @CherylC 's drag’n’drop of descendants and their spouses from Family View to Family View and merge the same person using her databases. That’s to replicate her RM10/Mac problem on RM10/Windows and to avoid introducing variables. But I’ve also started DND to an empty database and have identified erroneous parentage links arising that are not evident in the originating database and do not show in a GEDCOM export-import. Diagnosis is daunting…
I seem to have replied to myself rather than to you @nkess in my previous message. Having reviewed your August topic, I agree that you also reported erroneous parentage arising from drag’n’drop back then. I wonder how widespread this lineage data corruption may be.

Sorry should have said that I am using RM 10 on Windows 11–no dual monitors, no synching to the cloud etc
@rzamor1 I’m beginning to suspect pedigree collapse might be the trigger that causes RM10 drag’n’drop to cause parentage corruption in the target database but I’m not certain of it. I’ve found that even drag’n’drop into an empty database can result in it but it is less obvious than when it occurs from, say, a smaller database into a larger one as that raises the probability of wrong names popping out. DnD into an empty database also simplifies analysis and I’ve found that a 3-gen “Descendants and their spouses” from focus person Nancy Farr-1895 gives a few examples (2-gens: none, 4-gens: more). I’ve noted cousins marrying in her 3rd-gen. I’ll show a couple of cases identified by a query that gives these results:
| ChildID | FatherID | MotherID | FamilyID |
|---|---|---|---|
| 17 | 15 | 29531 | 14 |
| 25 | 5949 | 5948 | 41 |
| 28 | 5949 | 5948 | 41 |
| 73 | 20 | 25218 | 26 |
Any of the person IDs (RINs) greater than 84 (the number of people transferred) are corruptions caused by drag’n’drop. They are pointers to people in the source database that were not transferred. Had the destination database not been empty and had a person matching the transferred id, they would become a parent of the child as has been illustrated in reports by @nkess last August and @CherylC last November.
Case #1
Mary Truitt-29338 to Mary Truitt-17
Mary is the spouse of the grandson Martin L “Mark” Bradley and should be transferred in a 3-gen “Descendants and their spouses” drag’n’drop. But should her parents be? Her father was correctly transferred complete with all individual fact types; her mother was not. But Mary’s parental family to which her father’s family-type facts are tied is corrupted. He is now married to a RIN from the source database that does not exist in the target, 29531, because Candace Elizabeth Whitaker-29531 was not transferred.
I’m not sure that Pedigree collapse figures into this case. No child of Mary and Mark was transferred as they are 4th gen and should be excluded. Mary is not a descendant of Nancy.
Next case, next message…
Case #2:
Julia Carpenter-29632 to -25
Both the resulting Julia-25 and her brother William-28 are recorded as children of non-person parents in the target database having RINs 5948 and 5949 from the originating database in the target FamilyTable. The Marriage event for this couple has been transferred (as has the Place for it) as can be seen under the Parents tab “(m. 1858)”. Both Julia and William married descendants of Nancy and should be included. Should her parents? If so, it’s incomplete and a corruption. If not, it’s a corruption. Drag’n’drop should do one or the other correctly.
There’s a new problem alert in the target database for Harriet Anderson-5. She has two Birth events, one before her parents marriage and one after. It’s possible that it was marked as “Not a problem” in the original or the order of the Birth records in the EventTable has switched in the target. Neither is marked Primary in either database.
Again, nothing jumps out as a trigger. Her descendant- and only husband had a second wife and she has been transferred with no residual parentage so that seems to be by design. His second wife had a previous husband who was not transferred.
The later Birth event (1853) will be marked as primary once I have time to go through the combined database and clean up these issues. The sole source for the earlier Birth event (1845) is Harriet’s death certificate, while the other is supported by various censuses. So this at least is not an instance of a drag and drop problem.
Case #3
| ChildID | FatherID | MotherID | FamilyID |
|---|---|---|---|
| 73 | 20 | 25218 | 26 |
| William Hemp Farr-25219 to -73 |
This one definitely has incidence of pedigree collapse in it. Whether it is a triggering factor remains uncertain. William is the spouse of Nancy’s granddaughter Frankie Jane Anderson so he should be shown in a 3-gen Desc+spouse DnD. But his parental unit is also brought over, father David Jefferson Farr-25217 correctly identified and reassigned RIN=20 but his mother, Mary Jane Carpenter-25218, becomes a non-person identified by her original RIN=25218. Their Marriage and Marriage Licence events are also in David’s profile. That sounds like Case #1 but it gets more complicated. William’s father, David Jefferson Farr-25217/20 would be there anyway because his second wife, Frankie Emeline Bradley-25225/19 is also Nancy’s granddaughter. And, unexpectedly, 3 of their children also were transferred - that’s 4 generations when I specified 3. No parentage for David was transferred.
A further wrinkle is that David is 1st-gen person Nancy’s nephew but I doubt that is a contributing factor in a descendancy transfer.
