You may like to follow up an article in the Poor Law Unions Gazette of 10 December 1898 (and lots of other dates - same advert) - mentioning Frank Thompson (late of 2, Hampden Street, Somers Town), aged 34, and giving a physical description. It also says he was known at 22, Stanhope Street, Euston Road, and had five children. Presumably he had deserted his family - the usual reason for being in the Gazette.
Afterthought - probably not your man. If he was born in 1872 he would have been c.26, not 34.
