My Great Grandfather William Logan b 1856 Islington, married Caroline Amelia Zettel in 1883 Battersea. From family information her Parents were John Alexander Zettel 1841 and Caroline (Lunn). Her brothers and sisters were Babett 1865, Apelona Sarah 1868, John Alexander/Alexander John 1869 and Frederick Charles 1871. Rumor has it that either Babett or Apelona died in the California earthquake of 1906.
