Mary Lasceles

Mary Lascelles was born the second oldest child Sir Jonathan Lascelles and Lady Mary Lascelles (née Bruce). Her father was the second son of the late Sir Malcolm Lascelles, The 3rd Earl of Medford, thus Mary was styled as " The Noble Mary Lascelles" as the granddaughter of an Earl through the male-line.

Mary's birth was a bit dissapointing. The Lascelles family were hoping for the birth of a son. on Mary's birth there were only three individuals in line to succeeded to the title of "Earl of Medford", and all had either produced no living children or all daughters (Lady Barbra Lascelles; Cassandra Lascelles; Laura Lascelles; Josephine Lascelles; Francis Lascelles). With no male heir being born the succession to the title and the inheritance of the estates looked unclear.

It wasn't until the birth of Mary's younger brother Jonathan Lascelles that the inheritance was secured.

Mary grew up with her parents and siblings at Harlech Castle, along with her uncle The Earl and Countess of Medford and her cousin Lady Barbra Lascelles.
