I am new at this so pls be patient

I have been working on the Mossman line for over 20 yrs-am now back to finding our line in England, although I believe it is more Scotland. Our Arch(ibald) Mossman was 6 weeks old when his father George died. A: b 18 Jan 1771) G: b-Berwick Upon Tweed, d-4 Mar 1771. Believe George is buried in the cemetery at the Holy Trinity Church in Berw Up Tweed. Any idea who I can ask to get me a picture of his gravesite? Have no info about Arch's mother except her name was Eleanor. Am told George's father was "John of Scremerston". Some of our family has been told we descend from the John and James Mossman (1530-40ish) line - but others have tried to say we come from Ireland or Australia. I have no reason to doubt either, but my gut instinct tells me it is the John/James line. What would be your directions to find out more about John (the goldsymth for the crown) and his son James, who owned the Knox House (which was at the time named the Mossman House) who was hangit for his allegiance to Mary Queen of Scots, although I have also been told they were counterfeiting money in the castle when they were overrun. I need direction to uncles, brothers, nephews, etc, to trace down the lines. I was in Berw & Edinb in 1995, but due to my gross o/, I did not walk the church cemetery or was I able to talk to the genealogist in Berw. I just don't know who/how to contact to know what to do. What we DO know stops back at George Mos(s)man's death in 1771, apparently in Berwick Upon Tweed. George's wife, Eleanor, remarried after his death (she also died in Berwick). Archibald was "a Freeman in Berwick on 13 Jan 1792 and was admitted to the freedom as being the eldest son of George. The 1796 roll of Freemen stated that Archibald was a butcher and by this time living in America, indicating he would have had to have been in Berwick in 1792 in order to claim the Freedom, and then left England." Many have read the Mossman books by Mr Mossman, but he has been proven wrong regarding our Archibald, so I worry there could be other errors as well. Pls pardon my abbrev due to length - help - if I could swim that far I would leave for Great Britain tomorrow
