Hi Fiona,
Sorry I have not written but a few things came up.  Here is my info on my Kellys etc.
Jane/Jean McCormick born 1849 Ireland. She was the daughter of Alexander McCormick and Jane Andrew(s). She married Joseph Kelly abt 1871-75 St.John's P.G. On the census it states he was from Fife Kirkland and he was flax dresser born abt 1847.  I do not have any info on his parents or siblings which I really need.  Jane & Joseph had the following children: Jane  Elizabeth, Agnes,John,Joseph,Annie,Alexander  all born PG. lived at 9 Argyle Street, Joseph & Jane are buried Port Glasgow Cemetary he died 1920 and Jane 1937.  The names that all part of this same family are: McCormick, McCracken, Nicol, Tennyson,Martin,Andrews,Adam,Napier,Tough.  Did ANY of your Kellys ever live in Aberdeen  I would love to see your information and see if I can match anything or anyone.  Do you ever come up with anyone being called 'Pearl"? I think it is a pet name for Margaret? any opionions?
Looking forward to hear from you.  Thanks for taking the time.
Molly
