I am interested in contacting Allen Emmerson and Susan Emmerson. Their mother Doris Marjorie Emmerson (nee Allen) died in Calgary 2002. Her mother was Annie Barton born in Bideford, England 1887. I am trying to complete a family tree of all the descendants of John Barton b 1843 Bideford and Allen and Susan, hopefully, fill in some gaps for me. John Barton was my great grandfather.
