Hi You know that Naomi BOOTH nee KNOTT arrived in Alberta Sept 1921. to marry K/H/R? BOOTH.
You know that she returned to England in 1960.
Is there information re: Marital Status at that time ? Widow/ divorcee etc.
Is there information in England re any children?
Is Naomi still living ? - if not - perhaps an obituary may have been published - which may include name of late husband / children?
Any family letters/ photo/s etc - that may give you some leads.
Vital Events in Alberta - are not indexed /online.
You might want to contact Govt of Alberta Vital Statistics Registry Office - for advice. They may be able to advise how to find information re a marriage - without having to purchase a registration of marriage.[cost$40]
