Martin was born on a Friday at home in Bakerton. As Tommy and Maggie's first born child, he was given his name in memorial of his Great-Uncle Martin, who immigrated from Ireland during the 1830's. It is unclear where his middle name of "Dineen" originated, however "Dineen" is traditionally an old Irish Gaelic surname and may have been the maiden name of the wife of a Welsh man. Martin's only sibling was born two years later in the spring of 1894, and she took her name from the Flanagan family.

8 year old Martin is living in Bakerton with his parents and sister. His father, Thomas, notes that he is a day laborer, but had been out of work for six months the past year -- this was likely due to his quarry accident in 1899. Martin is listed as having attended school nine months out of the year.

The Shepherdstown Register reports that both Martin and his sister, Essie, completed the recent county examination and received a diploma. Both siblings were taught by Miss Rose Cockrell, of the Oak Grove Schoolhouse.
