Maghull's first school was founded in 1668 in a small cottage in School Lane with the headmaster being Humphries Webster, showing the town's emergence although County Rates from 1716 said of the town "Maghull doth always bear and pay a third less than either Down Holland or Lidyeat". This shows that Maghull was a developing community, but still not as rich as its neighbours Downholland and Lydiate. Economic development continued with the Molyneux family (Earls of Sefton) being significantly active in bringing about the Alt Drainage Act in 1779 which resulted in many acres of marsh land along the river eventually becoming good agricultural land. This had led to the growth of the population to 534, with about half the employment being in trade rather than agriculture and a rise in 1815 to a population of 720 people with 71 families engaged in agriculture and 29 in trade, manufactures and handicrafts. There were 108 inhabited houses.
