That's mostly true for the past, but not true for recent blessings. I don't know the exact date, but about 5 years ago the blessing forms were changed to include the MRN. So recent blessings could reliably be connected to a member by MRN. Before that, for decades it has been the practice to include the name of both parents. Cross-referencing the three names as well as the stake with membership records should produce a very high rate of accuracy.
