When the editor of Frank Leslie's Lady's Magazine, Ephraim Squier, had fallen ill, the then Miriam Folline Squier volunteered to fill in, and the ill editor still received the salary.
Mrs. Squier took on the position permanently; in 1873 she divorced her ill husband and shortly thereafter, about 1874, she and Leslie were married.
It was his second marriage, and her third.
Their summer home, Interlaken, was in Saratoga Springs, New York, where they entertained many notables.
In 1877, they undertook a lavish train trip from New York to San Francisco in the company of many friends.
Miriam Leslie wrote her book From Gotham to the Golden Gate telling the story of this trip.
The expense of this trip, and a business depression left Leslie's business badly in debt.

When Frank Leslie died in 1880, the debts amounted to $300,000, and his will was contested.
Miriam Leslie took the business in hand and put it on a paying basis, even going so far as to having her name legally changed to Frank Leslie in June 1881.
She was a notable feminist and author in her own right.
Both his and her remains are interred at Woodlawn Cemetery in The Bronx, New York City.
