After looking for more info about Catherine I can see she died at the time her daughter Isabelle was born in 1902 so I am left wondering about the following:
Edward Donald Timmons born 1899 and drafted in 1917 to WW1
Joanna Timmons born 1901 and living with Aunt Bella Morrison in 1910 census, Manhattan
Isabelle Timmons born 1902, Manhattan
These three children born to Catherine before she died have never been known in our family in Scotland. Did they die young? Did their father marry again and they lost touch with Aunt Bella. What happened to her after 1910? The Morrison girls habitually gave their ages as five years younger than it really was and the name Timmons is often written in forms as other things such as Timmins, Timmony etc. If anyone has info I would love to add it to the family history
