I really couldn't say, but i've always found the BIVR indexes a bit "hit & miss".
Occasionally though they do show the unexpected...
Like Thomas Hunam's record; his is the only "Hunnam" entry for Tranent.
Thomas is caught between his birth Dec 1854 (OPR) & his christening Jan 1855 (when Stat Records began).
Could this have anything to do with him not appearing on SP?
The CD box doesn't exactly explain what the indexes contain (it's the 2nd edition i have)
Though it does say,
"This is not a complete index; some counties in this set have been extracted more heavily than others"
Sorry this still doesn't answer the question....
