How to merge duplicates under LNAB and adopted last names

Question

John Maltby-1135 and Rachel Mason-1732 had three daughters:  Sally Ann Maltby-1815; Elizabeth Maltby-623; and Rebecca Wheeler Maltby-1745.
John died and Rachel married Medeef Eden who adopted the girls.  Now we have duplicate profiles as Sally Eden-98; Elizabeth Eden-95; and Rebecca
Eden-97.  How do I proceed to merge these sets of duplicates and show
the progression of names (before I tackle marriage names)?  How are the
birth father and adopted fathers names handled?

Answer 1

What I've been instructed to do in this situation:  retain Maltby as the Last Name at Birth (which would mean merging the Eden profiles into the Maltby profiles, with the Maltby profiles surviving), put Eden in the Other Last Name(s) field, and the married name in the Current Last Name field. Then you explain the adoption and the name change in the biography.

Edit: Forgot to add that you should put links to the adoptive parent(s) in the  child's bio, and a link to the adopted child in their bios - which can be included in your explanations in the biographies.
