For easy reference, I thought that it might be useful to record some of the census information here. (I have quite a bit more than this, but these are the immediately relevant extracts.)
Here are the census records for George Gilliland and his wife Jane Turbitt (mentioned above, and at the very start of this thread)
Drumar, Ballybay Rural - 1901 census

(* Ernest Gilliland - I have a copy of the book "At the Ford of the Birches, The History of Ballybay, its People & Vicinity" by James H Murnane & Paedar Murnane. The book includes a small blurred photograph of Ernest Gilliland leading an Orange Parade in Ballybay. The book mentions that the Orange Lodge had supported a pipe band since the early 1920s and lists Richie Gilliland and Ernie Gilliland as banner bearers. The book also lists Ernest Gilliland from Corfad as being a Sergeant Major in the NIH during the First World War.)
Census record for Joseph Gilliland and his wife Elizabeth Phillips (mentioned above) with the nephew of Jane Gilliland (nee Turbitt):
Ullinagh, Carrickatee - 1911 census
Joseph Gilliland, Head, Presbyterian, 59 years, Farmer, Married, born Monaghan
Lizzie Gilliland, Wife, Presbyterian, 61 years, [No occupation], Married for 36 years, 9 children born and 9 still alive, born Monaghan
William Gilliland, Son, Presbyterian, 21 years, Farmer's son, Single, born Monaghan
Agnes Gilliland, Daughter, Presbyterian, 23 years, Farmer's daughter, Single, born Monaghan
Ritchie Gilliland, Son, Presbyterian, 19 years, Farmer's son, Single, born Monaghan
Martin Gilliland, Son, Presbyterian, 13 years, Scholar, Single, born Monaghan
Eva Gilliland, Daughter, Presbyterian, 7 years, Scholar, Single, born Monaghan
Betty Reilly, Lodger, Roman Catholic, 81 years, Widow, born Monaghan
Thomas Turbitt, Visitor, Presbyterian, 17 years, Law Clerk General, Single, born Monghan.
As yet, I do not know who was the common ancestor to George Gilliland (husband of Jane Turbitt) and Joseph Gilliland (husband of Elizabeth Phillips). As noted already, Susan (who started this thread) believes that George Gilliland's parents were John Gilliland and Margaret Maxwell. Meanwhile, I know that Joseph Gilliland's parents were Joseph Gilliland and Ann Nelson. But, undoubtedly, these families are closely related.
As mentioned before, Joseph Gilliland (husband of Elizabeth Phillips) was the brother of my great-great-grandmother Ann Gilliland who married George Woods. By the time of the 1901 census, this Ann Gilliland (now Woods) was in Glasgow, with her son Thomas Woods listed as Head. But the census return also records a Gilliland visitor:
40 Kent Street, Glasgow - 1901 census
Thomas Woods, Head, Single, 26 years, Police Constable, born Ireland
Anne Woods, Mother, Married, 47 years, Housekeeper, born Ireland
Letitia Woods, Sister, Single, 26 years, Assistant Housekeeper, born Ireland
Robert Woods, Brother, Single, 22 years, Mason's Labourer, born Ireland
George Woods, Brother, Single, 17 years, Cabinet Maker, born Ireland
Joseph Woods, Brother, Single, 15 years, Message Boy (General), born Ireland
William Woods, Brother, Single, 13 years, Scholar, born Ireland
Isaac Woods, Brother, 5 years, [No occupation], born Ireland
Robert Gilliland, Visitor, Single, 21 years, Police Constable, born Ireland.
So far, I have been unable to identify this Robert Gilliland. I do not know who were this Robert's parents or what became of him.
As another side note, I have started a topic on this Monaghan forum about the family of Major David Nelson VC. Some of the same families which are connected to the Gillilands are mentioned in that post too.
Hope all this is of interest and helps join up our missing links.
