Neil Walker b? 1900 Family from Scotland

I am the great granddaughter of Muriel Curtis, and am looking for descendants of her and her husband, Neil Walker.They were from Prince Edward Is., Canada.Muriel was born in 1901 and died in 1987 in Minnesota in the USA.Muriel had 1 sister named Gladys and at least one brother.I don't know much of any information on Neil Walker other then he was from Scottish heritage, whether he came to Canada from Scotland or another family member I'm not sure.If anyone has any information, it would be greatly appreciated!

Thanks,
Jenna
