birth: Coleman Ross born 1795 co Cork
birth: Mary Walsh (it is very likely she was born in Cork as they married there which was the practice to marry in the bride's parish.If she was born in Cork there are 112 births between 1795-1815 for Mary Walsh in Cork so you'd need more identifying info to find her record)
