falgousts on Family Tree Circles

I am continuing my research on the maternal side of the Spinks family. The name is Eliza Jane Liscum, born 2 Mar 1871 in Roseneath, Alnwick Twp., Northumberland, Ontario, Canada. She is the daughter of George Liscum and Jemima Rosetta Jackson.. George was born 4 April 1834 presumably in Upper Canada. He married Jemima 1 Dec 1856 and Died 4 Dec 1874 in Roseneath, Northumberland, Ontario, Canada. After George's untimely death, Jemima remarried Peter Smith on 6 Feb 1878 in Hastings, Ontario, Canada in the Alderville Methodist Church.
Between George and Jemima, 5 children were born. The last, Ekiza Jane Liscum is my great grandmother. In all my research thus far, I draw a blank as to the parentage of both George Liscum and Jemima Rosetta Jackson. I have come across several Liscum's in the census records, but no way to connrect parentage. I think, but cannot prove that George's brother may have been Bailey and Maitland Liscum, but it is only a supposition. I have nothing concrete. I am anxious to crack this line and would be happy to share any of the information I have that might be helpful to anyone. It just seems to me that with birth and marriage registrations there should be parents listed someplace, but I am coming up blank. Any help would be appreciated.

My name is Serena Falgoust and I am researching my grandmother's paternal line, Spinks. I have the main line traced to 1625, but would appreciate any additional stories or history on the family. My great, great grandfather is Jacob Jonel Spinks. He was born in Bodney and immigrated to Canada sometime between 1861 and 1863. He is married to Eliza Bird, dtr of Henry Bird and Susan Partridge. I have no further information or parentage on them. Any assistance would be appreciated.
