I think it says Akibo, more commonly pronounced and written as Akiva. Both Yaakov (Jacob) and Akiva are names with a shared root word meaning heel but they are definitely separate names. Jacob could have been an easier secular name to go by. See if you can find a gravestone since you have the parents names, that may provide a Hebrew name and the name he was known by together.
