Thank you everyone. This is a bit of a puzzle. Joseph Stayner Eidmans was, apparently, the illegitimate son of Eliza Eidmann, who was a half sister to William Eidmann, in my tree. I met someone a few years ago with a similar surname and we have tried, subsequently, to see if there is a link. She always maintained that Ada was married to Joseph Stayner Eidmans, and her branch of the family was descended from them, through Frank. She had done a great deal of research and established that Joseph, and his descendants, were opticians. Since I have started on the trail, I have found that Joseph Stayner may have had two families - one with Marianne Varnham (first wife) and subsequently with Katherine Churchman, who he may have married but never lived with - now it would seem there is something in the fact that he may have had a third family with Ada Trapp! Only the certificates will tell, I will try and obtain them when I return to UK (away at moment in sun - but its raining which is why I started looking at this!). Also, I have left my research papers in UK which may also throw up some more info. I have a copy of Frank Eidmans' marriage certificate - he married Dorothy Robins - shown on 1901 census. All the help given is greatly appreciate.
