text: Grasscroft cant really be called a hamlet anymore. The area at the top of the hill is probably more correctly called Lydgate (as in the school & pub). The area is mainly suburban housing (much built in the 1950s) and I suppose it has several hundred houses, so place=suburb is probably more appropriate. Reference should be made to how Grotton etc are tagged. Effectively it's a suburb of Oldham even though closer to Greenfield (and historically in Yorkshire not Lancs).
