My great grandfather was Joseph Mathew Kearns b. 1882 d. 1937
He had 2 brothers: John T Kearns b. 1875
William A. Kearns b. 1873

Together they formed Kearns brothers monuments located at 211 greenpoint avenue Queens Ny

I am looking for verification information on John T. Kearns, William A. Kearns and their father Thomas Kearns.

Thomas Kearns was a blacksmith b. abt 1838 - 1847 married to Ellen Rohan around 1873
