There is a tree (one tree in many versions, ant tied to a private website, so no use linking) at MyHeritage where we get:
Elsbeth / Elisabeth Buser born 28 May 1741, Ziefen, Basel, Switzerland to Heinrich Buser and Anna Buser (geboren Rudin)
married to Jakob Furler 29 July 1766, Ziefen, Basel, Switzerland
mother to three daughters, Barbara 1767, Anna 1770 and Salome 1774
dead 21 May 1806, Ziefen, Basel, Switzerland
One doesn't get at the sources - but I wonder if the daughters may be found by FamilySearch. Elsbeth's baptism is on FamilySearch (as male, no image - I believe the transcription error theory)
