Roger was a Mercer by trade. A Mercer was a person who dealt with satins, silks and other fine, expensive cloths and how they were used to decorate fine clothes.

He went into politics and was elected Alderman of Northampton in 1616, Senior Bailiff in 1617 and Mayor in 1626.

On 3 June 1589 when Roger was 29, he married Ellen/Eleanor MAKERNES/MACHARNES, daughter of William MAKERNES/MACHARNES & Agnes HARRGAT, in Northampton, Northamptonshire, England. They had eleven children, six sons and five daughters.

His will was written on 12 April 1649 and proved on 22 February 1650. It is printed in full on pages 16-17 in Aaron Sargent's Sargent Genealogy of 1895. His son, Joseph, was named executor.
