The Tonge family were quite widespread over the Barton upon Irwell area. You can find many of them on IGI under Flixton, Manchester (the Parish Church of St Michaels). You may also find them at St Mary's Church in Eccles, which was the church which covered Barton at one time.
I have only just found my connection to the Tonge family, an Elizabeth Tonge, baptised at St Michaels in 1784 so as yet do not have many details of the family.
Where are you from now? If too far to do anything practically I may be able to offer some help if you need it, although I do not live in that area now (now in Cockermouth in Cumbria) but still have family in the Barton / Flixton area
