Why are records missing from the Scotland Births & Baptisms index
I am finding that records that I expect should be in the Scotland Births & Baptisms index are not there. My specific example are the children of William Ure (PID LHLK-B5D) and Christian Gray (PID KZK2-J2C).
Searching the Births & Baptism index
Returns one record (search criteria father William Ure; mother - Christian Gray
Rreturns 6 records (search criteria first parent name - William Ure; 2nd parent name - Christian Gray
Searching Find My Past
Returns 7 records. 3 records for Christian Ure (the first 2 on the list appear to be from FamilySearch! William is missing from this but examination of the actual OPR film image shows that an additional baptism was inserted between the parents names which may have confused the issue. William can be found in Find My Past using a more specific search.
I wanted to search the IGI but the records index by the Church and those created by user submissions were split in 2020. Searching the revised IGI returned the same results as searching the Scotland Births & Baptisms index -
Searching the user submitted information returned all the names but also duplicates
Finally, searching old microfiche at the local Family Search Centre I found all 6 baptisms on fiche 6025727 (Stirlingshire births and baptisms sorted by firstname) and 6025758 (same - sorted by surname). Both of these fiche stated the batch number as C114852 (Larbert baptisms 1663 to 1820) indexed by the Church.
My understanding is that ALL the records that were produced by the Church (ie "C" batch numbers) in the original IGI were transferred to the Births & Baptisms index - so where are they now. These are not the only records missing in the index. This is just one example.
My supposition is that inappropriate merging of records in Family Tree is causing index information to be impacted, which if true may be a major issue with the content of many indexes and not just the Scottish Births & Baptisms that I have used as an example. I certainly hope that I am wrong in my supposition. Can anyone provide any assistance in this issue.
Thanks in advance.
