Hi Marcie,
I'm not at all sure what information you do have (it could be on one of those bits of paper

), but I took a look at Margaret Laidlaw (neé Laing)'s death certificate for some clarification on her parentage.
Margaret Laidlaw died April 27th 1916 in Leith, aged about 72 years. Her parents were given as James Laing, brushmaker (deceased) and Elizabeth Laing m.s. [maiden surname] Melrose (also deceased). The death was registered by Margaret's niece, Elizabeth Blaney?.
Unfortunately there are only submitted entries for this family on the IGI .. children; Janet 1832 Edinburgh, Elizabeth 1837 Glasgow?, James 1838 Edinburgh, William 1842 Edinburgh, Margaret 1844 Edinburgh and Grace 1847 Edinburgh. However, there is an extracted entry from the OPRs helpfully showing Elizabeth's father. If you view the OPR, you will often find that an occupation will be listed for him too.
James LAING and Elizabeth MELROSE (daughter of James MELROSE), 18th June 1829 St Cuthberts, Edinburgh
This looks like the family in 1851 too:
