Hi all! This is my first post here, so I'd like to apologize in advance if I make any mistakes.
After a good deal of searching, I think I have located my grandfather and his sister in the Civil Registration Birth indexes for Northern Ireland on Family Search. Below is the relevant information from the entries. The dates in these entries match the ages which are recorded in the U.S. Census after they moved to the U.S., and I have a vague recollection from family lore that they were Orange Protestants from Northern Ireland, so I'm pretty confident I have the right people. There was also a (possibly older) brother named Mike Arthurs, who I haven't been able to find the least trace of beyond an entry on Find A Grave for his death in the 1903 coal mine disaster in Hanah Wyoming. Don't know what happened to his birth information, or what "Mike" might have been a nickname for.
Now I'd like to order the birth certificates for John and Lizzie Arthurs so I can find out who their parents were. Also, I'll need those documents for when I attempt to claim Irish citizenship. And I'm having some trouble figuring out how to go about it. It looks like I should apply to GRONI for the certificates, however they appear to require information such as the names of the parents and their addresses, both of which I have no idea about and had hoped to obtain from the certificates I wish to order. Also, it is my understanding that the volume and page number of the Birth Index entry can somehow be used to easily find the certificate, however I see no way to provide that info to GRONI on their form, and am uncertain of which of the numbers is important and of the proper way to format that information.
Can anyone provide some guidance on how I should proceed?
