Hi, I wondered if anyone had any information on Thomas Richard (Dick) Corkill

His gravestone (in the US) says he was born in 1813 and it is known that he spent a lot of his early life on the sea, perhaps with his father who may have been a fisherman or merchant.

He was married to a woman who we don't know and they had a child named Thomas Jr. My guess is they were married sometime between 1830 and 1835 and had the child a few years after that.

Thomas, his wife and Thomas Jr. apparently came to American to the State of Pennsylvania sometime between 1834 and 1840, I do not know the ship's name or manifest.

He returned to the Isle of Man, I believe in 1873, to visit his brother and stayed for about a year before returning in 1874 to the state of Illinois, he apparently brought his neice named Maria with him to America. He died soon afterward in 1875.

I can't find much info as there were quite a few Thomas Corkills and I can't find a Thomas Richard Corkill with dates that tie in. Would appreciate any help on this, thank you!
