Yes, it is called Scotland's People. You can get copies of bmd's from there. However, given the person you are researching was born in 1955, you wont be able to view her certificate online and will need to Order a copy.
They also have Census records, some Wills and some parish records.
SP operates a credit system, you can buy them in rising groups of £6. I think it costs one credit to view each page of a search and 5 credits to actually look at an entry.
Thank you both very much. Im trying to trace back further than the name above. She hasnt got her birth cert and thinks her mums maiden name was Laing, but not sure.
i will try that site, it may prove helpful. will let you know how I get on
Thanks again. Sorry I cant give both of you best answer but give you many many, thanks.
You can get census records back to 1841 on Ancestry. Have you been on the Scotland 's People website you can get birth, marriage and death records from 1856 also census from 1841-1910 plus Old Parish Register entries. Definitely worth looking at I've got files of records that I've printed off from there. It's very addictive!!!
