@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…
