Hi Gordon
I'm not surprised you haven't been able to find them......not sure where the Campbell name comes in.........!!!
I've found some of the births on IGI, I'll leave you to find the rest! The problem lies with John Snr. surname. Now he is either a late marriage for Susan or for some reason changed his name from MACKLEHERRING to Campbell.
Using the individual batch codes for IGI from
http://freepages.genealogy.rootsweb.com/~hughwallis/IGIBatchNumbers/CountryScotland.htmand searching under just mother Susan McLusky brought up the following entries, including your Rosann:
HUGH MCILHERRIN Birth: 28 MAY 1855 Blantyre, Lanark, Scotland
Parents: Father:
JOHN MCILHERRIN Mother: SUSAN MCLUSKIE
WILLIAM MACKLEHERRING Birth: 17 FEB 1870 Hamilton, Lanark, Scotland
Parents: Father:
JOHN MACKLEHERRING Mother: SUSAN MCLUSKY
MARGARET MACKLEHERRING Birth: 18 DEC 1871 Hamilton, Lanark, Scotland
Parents: Father:
JOHN MACKLEHERRING Mother: SUSAN MCLUSKY
ROSANN MACKLEHERRING Birth: 06 NOV 1873 Hamilton, Lanark, Scotland
Parents: Father:
JOHN MACKLEHERRING Mother: SUSAN MCCLUSKY
The rest of the births are probably there, in different areas, under spelling variants of Macleherring.
The 1855 cert. looks a good one to start with!
Regards.
