If you are looking for birth info on William McLaughlin in Co. Antrim, you might want to try checking your local LDS Family History Center. The civil registration of all birth, marriages, and deaths began in 1864. Would suggest you go to your local LDS. Starting with the year of birth you have, 1867, the LDS Film number you will need is #0101044. Look for him registered in the Ballymoney district. The index information will a volume and page number. Write them down. Ask the folks at the LDS about ordering the specific film. If there is more that one William listed, you may have to order more. I'm not sure of the cost, as I did my family many years ago here in the US. The final information will not only include place of birth (townland)), but will also include father's name and mother's maiden name. If you cannot find him in the year 1867, let me know and I will give you other LDS index file numbers that may be helpful.
Good luck.
