My Lomases are from Chapel-en-le-Frith (as far back as the 17th century and probably earlier) and never lived in Macclesfield.
But my wife has Lomas ancestors who were in Macclesfield in the 19th century. The father, James LOMAS was a silkspinner aged '40 years' living in Astbury, Congleton in 1841; living at 14 Fence St, Hurdsfield, Macclesfield in 1851 (labourer, aged 50 years born Wildboarclough) and 1861 ('formerly cotton factory worker', 66 years born Congleton). In 1859, from son Charles' marriage certificate, a labourer. He was in the Union Workhouse, Macclesfield, a widower, in 1871 (James b Gawsworth/Wincle was elsewhere, a farmer, in 1871 and 1881) and 1881, agricultural labourer aged 74 years born Macclesfield (1871) and cotton spinner aged 82 years born Wildboarclough (1881). A stone mason according to his death certificate.
I haven't found a christening for this James LOMAS. I reckon he was more likely born in Wildboarclough, his father possibly working at the newly-opened Gradbach Factory. One of the owners of that factory hailed from the N Staffs Moors so I speculate that James' father was a N Staffs Moors Lomas.
