M'Ilhagga births

When searching Ancestry.co.uk clearly most Births Marriages and Deaths (BMDs) would be revealed when using our commonest spellings McIlhagga, McIlhagger, McIlhaga, &c. And surely if the Mc became M', that is just a writing convention and the BMDs produced would duplicate what I already knew. Not a bit of it! Here, for a start, are the Births registered with the surname spelling M'Ilhagga. I have listed in ordinary type those I already had in my clan Birth Index. Those in italics were new to me. The place name is the Registration District and the figures give the volume and page number should anyone wish to apply for a birth certificate from the General Register Office. You will note that all the references are in Ulster:
