My first suggestion would be to look at the local phone book for Ballymoney. Some years ago, when a cousin of mine visited the town, she saw in the phone book that there were Loughheads living in Main Street, Ballymoney. If they are still there, they might be living in a property which was once owned by our ancestors, who seem to have owned a number of properties in the town. I have lost the paper my cousin gave me with the person's initial and street number on it, but I received no reply when I wrote to them. You might have better luck if you are bold enough to knock on their door.
Your great-great-great-grandfather Rev. Robert Loughhead was the fourth born son of James Loughhead who was a farmer in Monaghan parish, County Monaghan. I have never been able to discover any more about James Loughhead, and I know nothing of his other sons.
Rev Robert Loughhead died on 10 Dec 1844. He was buried in Ballymoney. His headstone said that he was for 28 years the minister of the Second Presbyterian Church in Ballymoney. The numbering and naming of the Presbyterian churches in Ballymoney can be a bit confusing. It might be helpful to know that prior to the union of the General Synod of Ulster with the Secession Synod, the Presbyterian church founded in 1834 was known as the Second Presbyterian Church of Ballymoney in connection with the General Synod of Ulster. Its name was changed to Third Ballymoney in 1840 because Trinity Church, having been established since 1815 as a seceder congregation, had become Second Ballymoney. The congregation of the "demoted" church eventually changed its name to St James' Church.
As he was licensed by the Burgher Presbytery of Monaghan (a strand within Presbyterianism), Rev. Robert may have been trained at Glasgow Burgher Theological Hall. He was licensed by the Presbytery of Monaghan (Burgher) in 1813. He was ordained on 21 Mar 1815 at Trinity Church (Burgher) in Ballymoney. He was the minister of Trinity Church in Ballymoney until 1835. He and his wife Elizabeth nee Stewart lived in Ballymoney. Rev. Robert was listed in Slaters Directory of 1824 under Ballymoney Gentry and Clergy.
He was suspended between 1835 and 1840 following accusations of intemperance and performing irregular marriages. He was restored on 9 June 1840. Through his wife he was landlord of Garryduff and he organized a congregation there, to which he was installed on 29 Oct.1840. He was responsible for starting the building of a new church at Garryduff, but the building was still unfinished at the time his successor Mr James Gamble was ordained on 18 August 1846.
Besides looking at the phone book and the Main Street in Ballymoney, I think it might be profitable for you to visit the older cemeteries in Ballymoney. I seem to remember that you have to gain access to the oldest one via a shop, but a local will tell you where it is. The Second Ballymoney Presbyterian church would be worth a visit too, as would the church and township of Garryduff. I don't know anyone who has been there.
Rev. Robert's surname has been variously recorded as Loughhead, Loughead, Loughheed, Lougheed and Longhead, so you will need to watch out for some creative spelling. I have, however, never seen the name hyphenated. I doubt that sober Presbyterians would have been into that sort of affectation.
Found this on a page in Gen Forum and thought it might be of interest, take care,
