Dear Family, Friends, and the Sisters of St. Joseph,
It is with the greatest respect and sympathy that I write this memorial for Sister Timothy who was my principle at St. Margaret's and was always a guiding light in my life. She was strong and opinionated and that is what made her teachings so honest and true to an individual. She loved and worked hard for St. Margaret's Parish, she gave us her all! I will miss our visits at the residence from time to time, but I know she is with our other beloved ones now especially in the hands of our beloved Lord Jesus Christ - May she rest in peace, AMEN!

Pat I am so sorry for your loss. My first teaching job was at St. Margaret's and Sister Timothy was the first principal I had ever worked for. She welcomed me with open arms and made my first year of teaching wonderful! I have many good memories from those 6 years. She was a beautiful person inside and out. Even after I got my teaching job in Canada we kept in touch. I still remember when you both met me in Fort Erie for a game of bingo. Our loss is heaven's gain. My deepest condolences.
