I think little Annie was the daughter of Annie Glover née Rosson who was the sister of Emma Georgina Rosson, Willie's second wife
Annie does not appear on the Family Tree above but her mother does, who is Annie Rosson born 1874 and it is assumed at this point of this website that Annie Rosson married a Glover
Notice there is a Higgs on the second page. That is Elizabeth Emma Higgs (my Aunt Liz or Liz & Rose fame)
