Thank you Jean, Joe, Monica, and Trish... for your time and kindness in providing these additional insights!
Jean - I suspect that you are correct in your assumption that perhaps the Alison family you mentioned living in Renton is likely related to Agnes, the wife of James Davie. (Note: James Davie's father (b: May 24, 1784 in Drumsaddoch, Cardross) is also named George...which I
assumed was the namesake of James and Agnes' son, George.) Can you please provide me the father's name of the Alison family living in Renton (husband of Henrietta) that you found? It might serve as a valuable resource for further research into Agnes's possible ancestors.
By the way, my ggggrandmother, Agnes, came to America alone with her son, George (according to family anecdotal records) in about 1848-49 - although I cannot find any ship records to confirm. She was reported to have died at sea during the journey. I found her husband James (who remained in Scotland...although I don't know why!!) living with a second wife and family in the 1881 census in Govan, Lanarkshire. His occupation is shown as a "carter". Do you know... is that a profession related to the printing industry? It may help to confirm that the family you referenced (and the Agnes that Joe referenced in his reply) are, in fact, related to my ggggrandmother...... I very much appreciate you efforts to help me.
ps. I went to scotlandspeople.gov.uk, but it said that "Due to the physical layout of the OPR's, the task of linking images to the correct indexes is proving problematic, and OPR images will not be available on Scotlandspeople in the short term future."
Joe - I have recorded the info you provided, as it may prove beneficial down the road in researching this couple. Do you know what month the 1841 census was taken? My records indicate that James was born Aug 19, 1819...which would have made him 21 or 22 (as opposed to 20)...but, I imagine such slight age discrepancies may have been commonplace(?). p.s. great to see a face with a name (...very handsome)

!!
Monica - I really appreciate the info you provided regarding a
different James Davie & wife, Agnes Gow. This info will prove very helpful so to ensure that I don't go down a wrong road and mistakenly assume this couple to be my direct relations.
Trish - Thank you for the batch/film number info you provided. I live in Shell Beach, California....I think the closest LDS centre is in Los Angeles...and I will make an effort to visit it the next time I am in Los Angeles. I'll be happy get you (or anyone else above) copies of records they would like when I'm there.
Thank you all again! You're wonderful!
