My Robert Meggison died in 1792 at the age of 62, as per gravestone, making him born about 1730. I have never been able to find a birth for him. I wonder if gravestone could possibly say age 67 making him born 1725 for which I do find a birth in Apr, with father Thomas, in Boldon, Co. Durham. As I am thinking his father might be Thomas, this might be possible. But I don't want to make things fit which really don't fit. However, there aren't as many Meggisons around as say Smith or Jones so the ones you find just might connect.
