Geograph - photograph every grid square

i have been looking for my grandmas place of birth so that i can come up and visit, she lived on a farm near a castle that my uncle pronounced castle cinniness, near glenluce, so i think i have found it now on the website!
her farm was also called castle sinniness apparently but i dont know if it is still there as the only photos i have are of my great grandma standing outside the farm but you cant see much and it looks very old! my uncle thinks there is now a bungalow built on the site where the farm was - i am so excited that we are coming up at may bank holiday and staying in glenluce. i will take my photo and show it anyone that looks remotely interested! my great grandma was called Holmes, she had 4 daughters, Ella, Janet, Bessie and Agnes (my grandma), her dad died on the farm around 1920, my grandma was around 7 years old when he died. i have tried to search on the surname on a website but no luck - would like to hear from anyone that lives in the area!
