My grt grt grt Grandfather worked at windsorlocks which is a damn as a child he was about 12 His name is Thomas F Danehy sr.He would have been either 1 or 2 when he came to usa or born with in a year of getting here. We do not know if he had any brothers or sisters since we lock up on searches with him. We do know that he married Katherine Kate Laverty and lived in CT about 30 miles from MA. I have info forward. Does match up at all? I know that this is not giving you the death info that you are looking for but if it matches maybe will help find him.
