On researching my family tree being Budge and later changed to burge I note that there was a marriage listed as having taken place between an Andrew Budge and Barbara Symison on 29.12.1842 in the area of South Ronaldsay.
Also there is a note of a christening of a Barbara Symison Budge who's father was William Budge and mother Margaret Symison . this was dated 5.10.1824
Another note is for a birth of a Daniel Budge with father David and mother Barbara Symison on 28.8.1791
Don't know whether this will be of any assistance to you
