1925 address is Warren Villa, Lodge Road, Coleraine
I wondered if the name of the house had anything to do with Warren Baxter who lived on Lodge Road (died 1927) so had a look at Valuation Revision Books (
www.proni.gov.uk)
In the book covering 1913-1931 (last one)-
75. Thomas O'Connor (Reps David Baxter) changed in 1918 to
John W. Rea (Warren Baxter)
John W. Rea married 20 Jan.1915 Belfast to Margaret Lea. It's likely that Margaret's mother stayed with them until she died (Eliza Lea, age 85, died 16 May 1945 Portstewart district).
