Leopold Lockhart was born in Concord, Massachusetts on February 14th, Season 28 [SHL Time] to parents Mark and Trisha Lockhart. Lockhart's parents divorced when he was seven, and Mark--an anesthesiologist--remarried two years later. Leopold sites his stepmother Vanessa as one of his biggest influences. He has two half-sisters Lilianna who is ten years younger, and Lisbeth who is twelve years younger. Lockhart started playing hockey in the Concord-Carlisle youth hockey program when he was six years old and attended various summer hockey camps and clinics. He also participated in youth Basketball, but eventually chose to focus solely on hockey when it became clear that he had a talent for it. Lockhart originally wanted to be a goalie, but changed his mind at age nine. This change of heart was due, in large part, to his love for New England Wolfpack defenseman Mia Landvik. Lockhart grew up attending Wolfpack games with his dad and hockey pals and counts a signed Landvik jersey as one of his prized possessions. Landvik signed the jersey at a home game on Lockhart's 10th birthday.
