Hi, What research have you already done ?
What are the names of your Great Grandparents -
You believe that your Grandmother Ida VANDALE -married COLGAN - may have been adopted
Many Provinces in Canada - have now opened Adoption records - these records may be available to your mother - or to you.. Well worth researching.
REGISTRATION of BIRTH - /Long Form Birth Certificate - If your mother had been adopted - the Birth Registration and Certificate - will be modified - to show the new surname - as well names of adoptive parents including maiden name of the mother.
HOSPITAL Records -re birth - these may be available - they would have the correct name of the birth mother - perhaps the birth father - if he chose to be named as birth father.
What month was your Grandmother born in 1920 1921 - She may appear in the 1921 Canada Census. NOTE: - Adoptive parents may choose a very different - given and middle name for the child that they adopt - names that they prefer.
