About Mary Costin

She was engaged to John “Jock” Law Hume: Violinist on Titianic

According to an article written by Christopher Ward (John and Mary’s grandson) in the Mail Online and updated on May 23, 2011, Mary Costin was pregnant with John’s child. Mary’s mother, Susan, told the story that in 1910, John and Mary had met at a town fair and it was love at first sight. Although they were separated frequently and his life aboard ship was lively and social, he remained true to Mary. One week before his departure on the Titanic she told him she was pregnant and he was “overjoyed”. They planned to marry when he returned.

From the beginning of their relationship John’s father felt that Mary was not good enough for John. Her father was a van driver whereas Andrew Hume was a music teacher and saw himself as a “man of position”. John’s mother has died from cancer and his father had remarried 14 months later. Since that time, the father/son relationship had been disintegrating.

When Mary went to the Hume residence to tell Andrew and his wife Alice that she was expecting John’s child, Andrew called her a slut and denied that the child was his son’s.

In fact, when he received John’s personal effects he refused to give Mary a momento. He also kept all of the hardship funds given to the victim’s dependents. He claimed he had “conclusive proof” that the child was no John’s. In answer to her appeal for funds, Mary received a letter from the Titanic Relief Fund suggesting she reapply after the birth and provide evidence of paternity. - See more at:
