I just came across your post. My grandfather was from Titusville, PA and his name was Theodore John Haaser (so I am guessing he was son of your great grandfather... My grandmother Adalaide Zaires actually married his brother first (but he died in the war).. It has been almost 9 years since you posted this--but I would be interested in what you have been able to discover. Thanks:) Lindsey Haaser my email is lindseyhaaser@gmail.com
