I'm not sure if there is any connection, but I have a Margaret Leitch born about 1814, who married Hugh Land Cuthbert in Antrim in 1835. Margaret's father was Robert Leitch, a linen weaver.
Hugh Land Cuthbert was born in Ballymena, Antrim in 1815. I haven't found Margaret's birth record, but it seems likely that she was also born somewhere in Antrim.
The date of their wedding in Antrim is from one of their children's birth records. I have not found the marriage record itself. Their first child was baptised in Ballymena at the Church of Ireland in 1836.
Hope you find this helpful.
