MY FERRIER 
Found this topic - so just putting this 'out there' - never know when a connection might be spotted by someone!
Fife OPR - born 12 October 1830, Agnes FERRIER, natural daughter of John FERRIER, Wright, Boarhills and of Agnes TURPIE daughter of the late John TURPIE Wright in Kingsbarns baptized.
This baptism indicates, Agnes FERRIER was illigitimately born? but she is baptised as FERRIER, is FERRIER in the Census 1841 & 1851, at her marriage 1857, in mms for births of her children and ms at her death in 1916. She was also sometimes named as "Nancy", a pet form of Agnes. Her father is named as John FERRIER on both her marriage & death records. Her mother Agnes TURPIE is stated age 40 in the 1841 Census but she could be as old as abt 44 (I haven't found her in 1851 nor her death anytime after 1841 (She is not the Agnes TURPIE living in Croft Dyke, Ceres in 1851 and 1861 who was Agnes nee SMITH/SMYTH b abt 1806, who died 1869, widow of TURPIE).
So - not sure who John FERRIER, my 3x Gt GF is.
Can find no trace of a John FERRIER in the 1841 Census for Boarhills Village or surrounds. But in the Boarhills census of 1841 and 1851, there is a David FERRIER, Shoemaker who was born 1784 St Andrews Fife to John FERRIER and Christian YOUNG. Possibly (probably) my John is related to this David. A son, brother, even a father etc. (I have no pre-conception of John's age based on his 'baby-mother'' Agnes TURPIE's age - he may have been a lot older or a lot younger than her).
The IGI has no sibling of David named as "John" (there is only one sibling recorded on IGI, a sister). However, David and his wife Barbara LESLIE did have a son named John - born 1812 in Boarhills. And it appears he may have been a Carpenter ( my John was a "Wright"). This John is about 11 to 15 years younger than Agnes TURPIE and he would have been only about 18 in 1830 when Agnes' illigitimate daughter was born while Agnes herself was at the least abt 32 at the time, and possibly was abt 36. A large age gap, but not outside the realms of possibility .
John FERRIER, son b 1812 of David and Barbara maybe the following on the Census 1841/1851 - he is also in Angus up until the 1881 Census (I haven't as yet purchased his death cert to confirm his parentage):

There was another FERRIER family associated with Boarhills - James Frederick FERRIER (1808-1864) , a Philosopher/Writer who later in life lived at "Westfield House" in Boarhills Fife from at least approx 1845 and died there. His father was John FERRIER of Edinburgh "writer to the signet" - who is probably the same John FERRIER who died at Arbroath, Angus in 16 April 1822 age 93, "long in his Majesty's Service" (The Edinburgh magazine and literary miscellany, Volume 89, 1822 page 696).
