Ernest fought and died in WW1 and is buried in Leamington. Lena's full name is Mary Evelina Girarden, then Livingstone, then Merrifield. I believe she is buried in Wheatley. I have never heard of David, Walter or James. Lewis and Mary had Iva, Vera, Annie, Jenny and I think 2 sons but I can't recall their names now. Lewis is buried in the cemetery in Point Pelee along with a daughter Victoria (died at 2 years of age). Vera was my grandmother. I am sure this will help. Please contact me, I have a paper family tree which is connected to the Livingstones in a small way. Enjoy!
