Jacob E. Wyke, the E. is for Ellsworth is my grandfather. He was born in 1862 and died in 1951. He was a civil war orphan, and was put into boarding school in Penn. I have all of his papers from the time he enlisted until he was commissioned. He served with Teddy Roosevelt and was Gen Perishings aide de camp. He is buried next to Pershing at the Presido in California. He married Helen Godfrey. Is this the same man you are looking for?
