Diggle family Lancs Bury

My GG Grandfather was Joseph Diggle, he married Elizabeth Ann Turner and he had a son Robert Diggle born 1879,also they had 2 other sons Walter(age 8 on 1891 census) and William(age4 on 1891 census), they are from st. Mary,Lancs Bury.
I think that Joseph's parents were William and Ellen Diggle from st thomas, they were cotton spinners. Joseph had a sister Alice J Diggle age 19 in 1871.Alice J. married William Roberts.

Does anyone have any connections to this part of my family tree? Would love to hear from anyone who does.
