Thanks, I just went through my a-z and found some duplicates and merged them. Back on my tree view there are still two of each cousins all side by side. As well as two John Hawkins (Marys dad). Its a headache to look at but flicking to the a-z now non of the people duplicated are duplicated on the list. Also on tree view I clicked on Sally Clatworthy who appears to have two husbands called John Hawkins but her profile only shows one.
Going to carry on having a fiddle about, I just managed to get rid of the extra John Hawkins. Flicking between three tabs while typing this:)
Thanks for your help
