Thank you for both replies. Have found Edith and Fred Styles sailing from Liverpool to Halifax 1912. Seems a positive find.
Have also tried Manitoba Stats site but no results shown, will try again.
Ellen Maud Marsh was Edith Emma's sister and they married two brothers, Walter and Frederick George E Styles. I've found Ellen's marriage but not Edith's. I'm pretty sure that Norman was Ellen's son, don't know about Thomas.
I do know that there was probably a daughter called Doris, could have been born in Canada, as I haven't found her so far on Freebmd site. I do have someone who could tell me about the family, a nephew of Edith's but he is very frail and is unable to help.
Will also contact Friends of Elmwood cemetery.
Thanks again, Maggie.
