Dear Ashley,
The subject of this discussion is a man named James Bruce. I have noticed this name, as the father of children, in only three baptisms registered at Dysart in the period before 1600. (1) For a male child, name not known, whose baptism was registered on 4 December 1586. (2) For a female child named Elspot Bruce whose baptism was registered on 27 February 1591. (3) For a male child named William Bruce whose baptism was registered on 27 May 1594.
Philip Paul Bruce, following a pedigree published by Geneanet, believes that James Bruce was born in 1570, and that he was the son of Sir George Bruce of Carnock and Lady Margaret Euphame Primrose, but a baptismal record cannot be found for him, and he is not mentioned in the Scots Peerage account of the family, or in the testament dative and inventory of Sir George Bruce of Carnock’s wife, Euphame Primrose.

I have looked at all three baptismal records, and although they are difficult to read it might reasonably be said that the father of each of these children was a resident of the burgh of Dysart in Fife, This is particularly clear in the baptismal record of William Bruce which opens as follows: "The xxvij day of May 1594. That William Bruce unlawful sone to [ Maisr] James Bruce In Dysart begotten in fornication wt Euffame Andersone [ baptised ] tht day ….. ."

I was following this record when I identified this man as "James Bruce in Dysart". He was probably a lawyer, and should perhaps have been designated as "Master James Bruce" (Master or Mr. being the title used by men who have graduated with the degree of Master of Arts) but I am less confident about his employment status.
In answer to your question about styles. In Scotland landowners usually add the name of their property to their surname. For example, If James Bruce was the heritable proprietor of Dysart he would have been styled "James Bruce of Dysart." If he was simply a resident of that place he would have been identified as "James Bruce in Dysart." If he was just a temporary resident, he would have been identified as "James Bruce at Dysart".
Sincerely,
Neil
