Brae is in the RC parish of Glenravel. Their records only start in 1825. Tracing the baptism of someone born in 1816 and their parents marriage will be very difficult due to the lack of records for the period you need.
The tithe applotment records for 1825 list 3 Duffin farms in Brae - Margaret (likely a widow), Michael & Patrick. One of them may be Francis’ parent. All look to have died by 1862 when Griffiths was compiled. Possibly Francis’ parents death brought him back from Glasgow c 1843, to take over the family farm?
