Thomas McCubbn (wife Emily) was my gg grandfather.
Thomas died late 1875 or early 1876 in Warrensburg MIssouri (his son said Thomas died an early age).
It is believed this Thomas McCubbn is the son of David McCubbin & Louisa Jane Gum.
How would I set out to verify Thomas McCubbn's parents?
Assistance is much appreciated; it is the one and only missing link in my McCubbin genealogy.
