Over the past couple of years I have noted half a dozen uses of the spelling McIllhagga and in particular I wrote about it on 16 May 2010. Each resource we use will of course vary in its use of our different spellings and each will make different errors in their transcriptions. For these reasons I have recently been noting how different spellings occur in Ancestry.co.uk. Nearly all are the same as in other sources such as findmypast, but for completeness I will now list the 'double l' versions, most of which are McIllhagga and all or most of which may go back to original sources:
