I need help. I'm trying to find out if Edward Karney is my 3rd great grandfather. He was born in 1804 in Ireland. He married Ellenora Jackson. I don't know that date. They had a son named William in 1832 in Canada. Edward came toAmerican in the 1830s and I believe lived in New York. William is buried in Goeway Osceola, Iowa. William married Mary Shanahan, she was from Cork Ireland. If anyone can help me I would sure appreciate it. I have been trying to find this line for a year. I''m stuck. Please help.
