We have a lot of McFarlanes in Dunbartonshire who all seemed to be in the textile trades. First I found a Patrick/Peter McFarlane born in 1770's who married Grizal/Grace Park of Old Kilpatrick. Their sons were John, 1807, b Bonhill, and Peter, 1824, b Glasgow. Peter had 4 more sons, John, Peter, Alexander and James, between 1855 and 1866. Another Park sister, Margaret, married a John McFarlane in 1788. So far I have found sons John b 1788 and Peter b 1807. Also in the picture was a James McFarlane born about 1800 in Dunbartonshire. Two of his sons were Peter and Alexander, born 1825 onward and found in 1861 census. These people lived in Bonhill, Luss, Alexandria, Cardross, Renton and sometimes in Glasgow. They were printfield workers or weavers. Do you think there is any connection with your McFarlanes? Is is possible to attach a document showing all the names and dates? I'm not too familiar with how you do that on this site.
