Don't know if I have the right page but here goes...

Train wreck in the early 1900's. Parents died leaving 3 young kids one of whom would be adopted by Afred and Elsie Boon of London, Ontario.

Kids names may have been Ann or Anna May, Bill, and Lillian.

Cousin recalls that a person took them to an orphanage and they may have been left under the surname Stewart or Steward

Sorry if this is not the right page!! but appreciate any help.
