Hello Kirsty,
Wester Balbeggie Farm, Middle Balbeggie Farm, Easter Balbeggie Farm & Balbeggie Cottage were all in Dysart Parish, Fife. Balbeggie Cottage is midway between Middle Balbeggie & Easter Balbeggie, on south side of Balbeggie Avenue (a farm road, not a street) just west, south west of Thornton village and north of Dunnikier Park Golf Course/Mitchelston Industrial Estate, Kirkcaldy.
There have been major changes in the Thornton area since your relatives lived there so not sure if it is still included in Dysart Parish.
Regards, Dod.
