Lavelle Killed in Action.
Pte. Leonard S. Lavelle, formerly sporting editor of the Stratford Herald, was killed in action. He went overseas in the spring with the W.O.R. [Western Ontario Regiment] Pte. Lavelle was widely known in Western Ontario hockey circles, playing for the junior, intermediate, and senior Stratford O.H.A. teams. He was regarded as one of the most aggressive men turned out in recent years in Stratford. He came of a family of athletes. Harry and Will being former well-known professional lacrosse players, Harry having played for Ottawa and Will for the Torontos. Two other brothers are overseas.
He was a member of the West All-Star junior hockey team that played the East at the Arena two winters ago.
His father, James Lavelle, is a well-known Grand Trunk Railway official in Western Ontario, and is more than having his share of trouble as it was only a week ago to-day that Charlie, his second oldest son, was buried at Stratford after succumbing to an attack of influenza, which developed into pneumonia. Charlie was a well-known lacrosse player for Durham, his home town, some years ago.

War Diary of the 18th Battalion CEF 
Theresa is a typo on the reprint of the newspaper clipping in the title. Lavelle is spelled Lavalle. Just to let you know. You don’t have to post this comment. Thanks again! This is more than I could have found in a long time. 🙂
Theresa,
Thank you for the information. I really do appreciate knowing this and if there are any errors or inconsistencies in my post regarding your family please do let me know.

Hi Eric! My Dad found some more info about my family. His Grandfather was William Anthony Lavelle and brother to Len, Lou and Russ. My Dad found a service number for William Anthony Lavelle for WW1 it is CEF 3135300. We never knew that he had signed up and have no other information about his WW1 service. We now know that 4 Lavelle brothers were WW1 soldiers. If you could find any information about William that would be so great. We thank you for all the amazing work you are doing for our family and so many families. 🙂
Thank you,
Theresa

Theresa,
Was William Anthony Lavelle married to a Mae Diza Tevlin? See this picture.
Theresa,
I have updated the primary blog post and added William Anthony Lavelle. I was able to find pictures of the gravestones for him and Lewis Edward. Please take a look at the soldier pages and confirm that I have it right. Please re-read the blog post and make sure I did not miss anything. Sometimes a writer is too close to his work and misses stuff.
Thanks again!
Eric
My Dad is also named after these men. William Leonard Lavelle, and these names are used many times in our family tree. A strong sense of family pride! 🙂
Yes that’s him! They are my Great Grandparents. Mae is my middle name! 🙂
I am reading it all now and will let you know! Thank you! 🙂
