- John Langshaw senior (1718-98) was the organist of Lancaster Parish Church between 1772 and his death. A lengthy correspondence between Langshaw and Charles Wesley and his sons, exists at Emory University in the United States and has recently (1993) been published.

- John Langshaw junior (b.?1763) was educated chiefly in Lancaster where his father was the organist at the parish church. In 1779 he went to London where he studied the organ under Charles Wesley junior. He succeeded his father at Lancaster in 1798 and frequently gave concerts of piano music. Langshaw also published many compositions for the church. Source: Dictionary of National Biography.
From John Langshaw in Lancaster. Today his son Jack received a very agreeable letter from [Samuel] Wesley and Langshaw hopes that the friendship of these two young men will be a long and pleasant one. Jack owes a great deal to Charles's sons.
Jack's playing has improved but his father cannot get him to compose. He seems to want the pleasure of writing music but without the hard work. He wishes that Jack would not underestimate his abilities in that area.
Jack is now organist at their chapel, for which he received eleven guineas a year. It has been promised that Jack will succeed his father [as organist at Lancaster Parish Church] and will then be paid £100 per annum.
Langshaw would be obliged to receive another letter from Charles as it has been a long time since they communicated. He understands that 'you have had my brother lately'. It is unclear when Jack will be able to visit London as they now have two organs to attend to. Langshaw has another son aged ten, who he is training for the organ. If the boy and his father lives, then Jack may be able to find the time to come to London in a year or two.
It is reported that the Prince of Wales [George] is visiting the estate [Knowsley Hall] of the Earl of Derby [Edward Stanley] near Liverpool.
