What is the full name of the father of the child to the woman who journeys west?  Answer the above question based on the context below:  Set during the American Civil War, the story focuses on Charlotte Lovell and her cousin Delia, whose wedding day is disrupted when her former fiance Clem Spender returns following a two-year absence. Delia proceeds to marry Jim Ralston, and Charlotte comforts Clem, who enlists in the Union Army and is later killed in battle. Shortly after his death, Charlotte discovers she is pregnant with Clem's child, and in order to escape the stigma of an illegitimate child, she journeys West to have her baby, a daughter she names Clementina (or "Tina"). Following the end of the war, Charlotte and Tina relocate to Philadelphia, where Charlotte opens an orphanage. Delia is the mother of two children, and Charlotte is engaged to marry Joe Ralston, her cousin's brother-in-law. On her wedding day, Charlotte tells Delia that Tina is her child by Clem, and Delia stops Joe from marrying Charlotte by telling him that she is in poor health. The cousins become estranged, but when Jim is killed in a horse riding accident, Delia invites Charlotte and Tina to move in with her and her children. Tina, unaware Charlotte is her birth mother, assumes the role of Delia's daughter and calls Charlotte her aunt. Fifteen years pass, and Tina is engaged to wealthy Lanning Halsey. Still unaware Charlotte is her mother, she begins to resent what she considers her interference in her life, and when Delia offers to formally adopt Tina in order to provide her with a reputable name and a prominent position in society, she gladly accepts. Charlotte intends to tell Tina the truth before her wedding but finds herself unable to do so.
