I have a problem. I am not sure of the convention or rule governing the correct use, or not, of the initial capital letter of a name or the first letter of a sentence when the original capital letter has been replaced by an apostrophe, as in written dialect, for instance. e.g. - "Mr. 'Ammond..." or "Mr. 'ammond...". "'E 'ad it, Miss." or "'e 'ad it, Miss."
Any help would be most gratefully received!
Many thanks.
Hi Skyliner, and welcome to English Forums.

I believe that in novels I've read in which the characters are shows speaking in dialects, they keep the convention of capitalizing the first letter, so "Mr. 'Ammond" and "'E 'ad it, Miss," would be what I expect to see. If you leave out the capital letters, you'll look like you're trying to write like e.e. cummings.
Many thanks Grammar Geek,
Your reply makes for great relief as I had had conflicting advice and the prospect of correcting a 400 page MSS was not an appealing one!
