Thank you so much for your help! The John Edward McNamara you found is definitely my GGF. He was born in Holland, Erie County, NY in 1873. Unfortunately, all BMD records were burned in a fire. Nothing before 1884 exists. Even NYS doesn't have the records before 1881.
If it would be helpful to you, I would be glad to send you scans of the documents I have. Just let me know and I'll email them to you.
