Source: Civil Marriage of his son, John Boyd, who married Margaret Anderson in 1864.
This also has to be the Andrew from Ballyclough, aged 61, who died in 1861, because that Andrew's headstone is within the same railings as John of The Collins, 1831-1904 in Ballylintagh Graveyard.
Is this man also the Andrew Boyd in Crosscanley in the 1831 Census? It seems likely as he lived in a household of three males and one female and this Andrew would have been married with two sons in 1831.
There are no Boyds in Ballyclough in the TAB.
