Sarah Elizabeth Harrison

I am looking for information on Sarah (Sadie) Elizabeth Harrison-born 1896 in England.  Her parents were George Wm. Harrison & Elizabeth Ann Smithson.  Sarah immigrated to Canada in 1907 with her father and his spouse, Elizabeth Mary Lingwood.  Sarah would have been about 11 years old.  Family members say that Sarah was never talked about-her mother and a sister were left in England.  Sarah had a son, Garnet Featherstone.  Would appreciate any info on Sarah and/or Garnet Featherstone or the Featherstone family.
