The Lawrence city directories have John with a few different spellings of his last name - 1888 has Liversage, 1894 & 1898-1900 has Liversedge, and thereafter it seems to be Liversidge.
There's a marriage for a John Liversidge in Lawrence from 1894 on the index I mentioned above. The only Sarah on the same page has the surname Edgerton.
I found a tree on Ancestry that I think might have your Leather connection - it lists Sarah Egerton born Northwich, England, married to John Liversidge, and died 1928 in Lawrence, Mass. Her parents are listed as Charles Egerton & Elizabeth Leather. Elizabeth was born 1842 in Hertsford, Chesire and died 25 Dec. 1937 in Northwich Chesire.
