The following is an extract from the MyHeritage Blog:
Today we've extended the popular record extraction feature that lets you extract information from a historical record directly to a relevant family tree profile, to now extract to multiple profiles. Thus, when you've found a record with information on several relatives, you can easily extract the information into all relevant family tree profiles.
How does it work?
Saving a record found in SuperSearch, or via a confirmed Record Match, to your tree creates an association between the record and the individual profile in your tree. It ensures that you won't forget the connection and helps you differentiate between records you've already processed and new finds. Once the connection has been established, you can extract information from the record into the tree profile. This enhances your family tree by adding more information from the record.
Many historical documents contain information about several relatives, not just one family member. For example, marriage records typically contain information about the husband and wife, and sometimes also their parents. Most census records cover an entire household.
Now you can extract information from a record found in SuperSearch or from a Record Match into multiple profiles on your family tree on MyHeritage - all at once.
