A Robert Bycraft died in Ashtabula Ohio in !880. If this is your ancestor he was born in Lincolnshire in 1840. While my evidence at this stage is slim, he appears to be the son of one of James, Simon, or Richard whose father was Richard. James, Simon and Richard appear to have had two sisters Joan and Ann as well as brother Edward ( who didn't have a son Robert as far as I know, and brother David who was my GG Grandfather. I am the only Robert in David's line. This is all based on the trend of naming people after their ancestors and the fact that all were Yorkshire or Lincolnshire people. I have little other evidence.
