I used LDS Microfiche numbers 6340933-6341018, covering the time frame 1787-1886 to search the Glasgow commercial and post-office directories for my McLea family. Dates for which there are no relevant entries are not listed. Relevant entries include names of this form: M'Lae, M'Lay, M'Lea and similar. (Page numbers are listed where I wrote them down, but may not have been noted.) NOTE: List is comprehensive for names of this type through 1852.
1853 has a partial list of these names, and afterwards only potential relatives of mine are listed, since it was becoming a pain to write down all the names which were probably not really related to me!

I found my ancestor John McLea, blacksmith, as well as his son Peter McLea, also a smith, and Peter's son Peter jr. who was an upholsterer and cabinetmaker. Potential other relatives are also included, and some of those not known to be relatives NOW may someday be known to be! These data help me narrow the dates of John's death to 1833-1840. Very useful, though I was hoping for even more specific dates! Of course other McLeas in the books have their wives appear in the book the year after their deaths as "Mrs. John," etc. It would have made my search even more useful if my family had been so accommodating, but I think they must have been hiding from the law or something! (Just kidding! But they did seem to avoid having records made of them!)

Here's the file: 1787-1886_Glasgow_Directories.doc. Hope it's helpful!
