I think you may be a distant cousin of mine.I read the following post on Genealogy.com:
"I am the son of Harry D. Tonks, son of Russell A. Tonks. Russell is the son of Ada Perkins of Birmingham, England, and Harry, your great-great-grandmother's(Sarah) brother. I believe Harry and Thomas may have been partners in a button factory at one time."
My father was Richard Lawrence Tonks who was the son of Harry Charles Tonks who died in 1951 and was the brother of Russell Tonks of New Jersey and my Great Uncle.Is this the same Russell that is your grandfather. I think he may be as I have button factory artifacts in my possession.
If so, I only remember speaking to him a couple of times as he would look in on my Grandmother, his sister in law, Claire Tonks when she was suffering in a rest home from 1965 to the date of her death in 1975. The last time I spoke with Uncle Russell was when my father died in 1978.
Sorry for the long message, just trying to confirm the ancestry.
