Task: Question Answering
Input (English): Robert and Mamie Eunson (Cameron Mitchell and Glynis Johns) are Scots who have just landed in America (the year is 1856), having been invited there by Mamie's uncle. They arrive in the tiny logging village of Eureka, only to be informed that the uncle has died when his cabin has been incinerated in a house fire. The Eunsons are assisted by the friendly locals in reconstructing the house and Robert takes to tipping timber. Mamie is heavily pregnant upon their reaching Eureka; she delivers baby Robbie soon after the cabin is completed. Robert first works for a logging camp as a lumberjack. He eventually wins over Tom Cullen the cruel Irish-American lumber-camp boss. Later Robert starts a successful boat building business and Mamie gives birth to five more children: Jimmy, Kirk, Annabelle, Elizabeth, and Jane.  The Eunsons are prospering and happy until little Kirk is diagnosed with diphtheria. Mamie and Kirk are quarantined while Robert takes the other children away. The boy recovers, but the goodbye kiss Kirk gave his Dadda before his departure proves fatal, and Robert succumbs. Mamie takes to working as a seamstress and Robbie becomes the man of the house. Things stabilize, but only briefly: tired and work-worn, Mamie contracts typhoid. Knowing she will not survive, she charges Robbie, her eldest, with finding good homes for his siblings, with families that have children, so they will not be lonely. 
Question: What is the first name of the person who eventually wins over a cruel Irish-American lumber-camp boss?
