Langstaffs in Saskatchewan Canada

I have been searching for any available information on my branch of the Langstaff family for many years.The family resides in Saskatchewan Canada but I have no idea where they came from or who the ancestors are, other than the fact that we are Irish.
My Mother was Viola Margaret Langstaff.Her parents were William and Wilma Langstaff of Grandora Saskatchewan.My mother's siblings were Evelyn, David, Ken, Donna, Shirley, Carl and Butch.If anyone knows ANYTHING about this family, please contact me at mwanner@shaw.ca.I would truly appreciate it!
