Recorded in several spelling forms including Rosted, Rusted, Rustadge, Rustich, Rustidge, Rustage, Rustedge, and possibly others, this is an English locational surname. It has two possible origins. The first is from a now 'lost' pre medieval place called 'Hrist - hrycg' or similar, and meaning 'the ridge covered by brushwood'. A second possible origin is as a transposed form of some other surname or place name such as 'Routledge', which has the same meaning. When researching surnames it has always to be considered that upto the 19th century fewer than 10% of the population anywhere in the world could both write their name and read even simple sentences. In addition local accents were very 'strong', and sometimes almost another language. The reasons why some five thousand medieval sites in England alone have disappeared are complex. These include disease particularly plague,civil war, and the development of sheep farming, which from the 14th century required far fewer workers than arable farming, and was much more profiable for land owners. The surname in the spelling of Rustich and Rustidge, has been relatively popular in Lancashire since the 17th century, and it is possible that the village was sited in these parts.
