Sandra,
There is a Joseph Crawford in Griffiths Valuation for Gortfad. He had plot 36 which was a 17 acre farm. He also rented an outbuilding on plot 37. Today that’s off the B96 road north out of Portglenone. However he appears to have been married to Ellen Crawford (ie maiden name Crawford) born c 1829. Died 1898. Not to Eliza Barkley. So perhaps there were 2 Joseph Crawfords in Gortfad, or perhaps there’s a mistake over what became of Eliza Barkley?

This could be Joseph’s death in Gortfad in 1901:

Joseph married in 1856. Neither he nor his bride had been married before:

Probate abstracts:
Probate of the Will of Joseph Crawford late of Gortfad County Antrim Farmer who died 28 September 1901 granted at Belfast to Robert J. Crawford and William M.Speers Farmers.
Above will can be read on-line on the PRONI wills site. It mentions sons James & Thomas and daughter Agnes Robinson. Robert Crawford of Lisrodden was one of the executors, so is presumably relate din some way. That family is buried in Portglenone Church of Ireland graveyard.
Crawford John Barclay of Gortfad county Antrim farm labourer died 6 January 1938 Administration Belfast 18 May to Thomas Crawford farm labourer. Effects £38 14s. 8d.
Crawford James of Gortfad Portglenone county Antrim farmer died 28 January 1957 Administration Belfast 20 March to Robert John Crawford milk roundsman. Effects £336 4s.
Both the above died intestate. Their probate files should be in PRONI (in paper format) and can be viewed there free. They should details their next of kin.
I am also struggling to find much on Hugh Barkley married to Elizabeth. Griffiths does have a Hugh Bartley senior on plot 8 in Killycoogan a 21 acre farm and Hugh Bartley junior on plot 9a which was a 27 acre farm. Both are deleted in 1870 and replaced by James Bartley. James is deleted from plot 8 in 1890 but remains on plot 9. By 1894 it’s John Bartley.
Judging by the 1901 census, James had retired and given the farm to John:

Barkley Matthew of Killycoogan county Antrim farmer died 21 September 1934 Probate Belfast 18 October to Jeanette Barkley the widow and John Gordon Barkley farmer. Effects £221 2s.
I cannot find deaths for either of the Hughs in Killycoogan in Griffiths nor for a wife Elizabeth. This grave in Aughnahoy Old graveyard seems to related to the Killycoogan family:
In loving memory of John Barkley, died 30th March 1923. James Barkley, son … 28th July 1922 Matthew Barkley, son … 21st Sept. 1934 Maggie Barkley, daughter … 18th March 1946. Mary Jane Barkley, … 19th Nov. 1946. Jeannette R Barkley, … 11th July 1964. Wife of Matthew Barkley. Tessa, wife of J G Barkley, ... 11th May 1968.
There are also Barkley graves in Portglenone Church of Ireland but I can’t link any directly to this family.
