I am interested in finding the immigration records for my great-grandfather, Thomas D. Davies, (12/18/1840 - 1/16/1907). He was born in Merthyr Tydfil, Wales and died in Cleveland, OH on the date above. He was a Blacksmith by trade and came to America between 1867 and 1869. He was married to Catherine Rees Davies (died Cleveland, OH 10/04/1906). I have been unable to find any information about what ship he came on or the exact date. Thank you for any help you can provide on this matter.
