George Henry Leighton in 1884 married Fanny Louisa Foster, who was born in Hastings. They went to live at 44 George Street in the Old Town, just behind Marine Parade.  Their first child, Caroline Amelia Leighton, was born in 1885.  She was followed by George Alfred Leighton in 1889 and Elsie May Leighton in 1891.  In 1891 Census, address is given as 45 George Street.

Kelly's 1895 Sussex Directory lists George Leighton & Co. as tailors at 44a George Street. The "& Co." may be a reference to George's brother, Charles, who in 1891 was employed as a tailor at Linslade in Buckinghamshire.  Charles moved back to Hastings and may for a few years have joined George at George Street.  By 1899 he set up on his own as a tailor at 185 Queens Road, Hastings.
