Hello
I am descended from the Deans family - Eliza Deans - Jane Dean's sister - she was my great, great grandmother, and therefore I am also descended from Margaret Geddes.
I share the same frustration about her death record not supplying her parents details but am trying to find out more on the Geddes line. One thing i do know is that they are from, in and around, Killinchy in County Down (as were the Deans). There was a cluster of Geddes family members in that area and are graves going back to the 1700s - but as yet I can't find proof of who Margaret's parents were.
I am aware from your postings that you have carried out research on the Scottish side, but just to let you know that I have carried out extensive research on the Deans - Hugh + Margaret + their 4 daughters - Eliza, Margaret, Jessie and Jane. As I say, i am descended from Eliza and have a MASSIVE family tree stemming from her. Margaret and her family went to England and I have begun to trace their descendants. Jessie Deans migrated to Canada in 1911 with her family and I have significant details on them and some of their details. With regard to your direct ancestor Jane - I have a photo of her and her husband and a number of her descendants and have traced and been in contact with current relatives. I'm happy to share this information with you if you haven't already got it.
By the way, if you are JANE, who I have already made contact with, please forgive me Jane, I can't tell from this who you are.
Regards
Tom Donnelly - descendant of Margaret Geddes
