The Library is the heart of the Ada Collection
All certificates related to the family contain valuable information and there is a form for each type. Sometimes the witness in a death certificate provides unique evidence of the existence of a child.
Wills can be uploaded to the AdaCollection in PDF format, then transcribed so they become searchable, and then converted to TST Documents. Wills are especially useful as they usually list family members in age order and mention places and heirlooms.
TST (The Surname Tree) Documents are an important feature of The Surname Tree as they enable you to great Wiki format documents containing links to relatives listed in the document. This is especially important in family ancestry where sons often have the same name as their parent and it can be difficult to work out which relative is being referred to.
