Mira's paternal patriarch, William Mark McKinney, conceived the innovative notion of compiling the comprehensive New York State legislation into concise, easily digestible, and logically organized volumes for the benefit of attorneys to reference during courtroom proceedings. This pioneering endeavor has resulted in the enduring and authoritative publication, "McKinney's Consolidated Laws of New York Annotated", which remains an indispensable resource in the legal profession to this day.
William McKinney, Mira's father, was a seasoned lawyer in his own right, with a deep understanding of the intricacies of the law. During Mira's childhood, her family resided in close proximity to the esteemed Theodore Roosevelt on Long Island, fostering a unique opportunity for Mira and her sibling, John, to engage in playful interactions with the Roosevelt children, forming lasting bonds and cherished memories.
