I have worked with databases that I have created from FamilySearch records. I systematically work through them to improve the records in places my ancestors have lived. Over and over again, I estimate marriage dates (and places) as one year earlier than the birth year of the first known child. I then estimate the birth year for the two spouses. What if FamilySearch were to ask something like this: Would you like FS to estimate the year (and place) of this couple's marriage information? Would you like FS to estimate the birth year (and place) for each of the two spouses? For those of us working with large numbers of entries, this would save a great deal of time and would also improve the collective tree much more quickly.
