hi clare,
i have never been to scotland in my life but i searched to see if lenzie was in a diferent county in years gone by, and yes it is dunbartonshire and kirkintilloch, but when i found the site mentioned below i found that for some time from 1669 that it was in aberdeenshire,
possibly there is another lenzie i really do not know but the info is there in black and white as they say, from the scottish roots ancestral research services, take a look at there site,
with all the best wishes for christmas and the new year, kali.
