Hi MF
I don't have the name of the Douglas father of Mary, George and James. I also have an unknown son due to mention of three cousins (William Douglas of Kilmore, James Douglas of Lurgan & Jane Douglas who married Thomas Jones) in the wills who don't have a clear connection to either of the named three siblings. We think that the father of these 4 (Mary, George, James and unknown) is either a John, George or James.
The Anne Douglas that I have a picture of is the daughter of the James Douglas who settled in Edinburgh (Lived in a home called Lurgan Place). She resembles my x3 great Aunt Margaret Douglas. You won't have her information as I am yet to find the conclusive verification that ties our families. As I shared before, I am quite certain that this Douglas family is related to mine but I think that the records that would prove our connection would be in the early 1700's (if they exist!). What I really need is a surviving male Douglas from this line who would be willing to submit DNA ... it wouldn't tell us when we connect, but would confirm if we are family. As yet, I have not found a surviving Male Douglas line for this family.
Mary Douglas married John Falloon, brother of Samuel Falloon. I've seen Rev Charles Falloon, but don't know what his relationship would be to John or Samuel.
It is John Douglas's son, George Douglas, who married his cousin Mary Gilbert. John Douglas was married twice, first to Mary Ross and then to Arabella last name unknown. George a son from John's first marriage.
George and Mary Douglas nee Gilbert had two daughters: Sarah Douglas (Birth 01 Jun 1873 in Lurgan Death before 1901 in Lurgan, Armagh, N Ireland ) and Mary Douglas (Birth 09 Oct 1874 in Lurgan, County Armagh, Ireland Death before 1901 in Lurgan, Armagh, N Ireland ). the 1901 & 1911 census has Mary Douglas living on William St. 1911 Census seems to show that her girls had passed away.
Does this help? Do you want more on the Douglas family?
