Alfred Michael King Trying to find any information on the above who is my GGF All immediate relatives are dead so have could against a brick wall. Here,s what I have Alfred Michael King born: ?? married Margaret Edgar and certainly lived in Belfast in 1925. They had at least 2 children... Alfred Michael King (GF) born:11-10 -1987. died: 20-02-1965 married Sarah Trowbidge on 22-07- 1925. Lived in Belfast. They had 2 sons Edward Henry King (my father) & Michael Alfred King. Edward Henry King. Born 06-07-1926 died: 19-08-1979. married Violet Lutton. They had 2 sons Michael Edward King (me) & Robert King. The other possible links I have are Grandfather had a sister called Rachel born 15-12-1895 and both were born in Cambrai St in Belfast. She may have gone to America or Canada. Another name seen is Florence King she attended the wedding in 1925. Another possible link is a letter to my grandparent in 1960's from a KATHLEEN and she calls them Aunt & Uncle. At this time she worked as a nurse in Bengough Rural Municipal Hospital in Canada and had recently lossed her Mother ( was this Rachel??) She makes reference to an Aunt Minnie who died in November 196? burried in Regina in Canada. That's it hope someone can help and I awit with interest? Michael King.
