Find Ancestors

I am trying to find relatives of my late Grandmother Sarah Louisa Slater (nee WALKER), who was married to my late Grandfather Ronald Leslie Slater.They had 5 children together,Terrence George(known as Terry),Roger,Lesley,Stephanie Louise(my mother) and Patricia Anne(known as Anne). My Grandmother Sarah was born in Ashbourne,Derbyshire on 19/10/1913 and I believe she had 2 brothers named Charles Henry Walker and George Walker,who were both born in Ashbourne<Derbyshire too,however I do not have any d.o.b's for them. Sarah's Father was called George Henry Walker and her Mother was called either Ethel or Enid Walker (nee TANNER). Sarah's brother George Walker married a woman named Kathleen (i do not know her maiden name) and they had 7 children together,named, John, Margaret, Charles(now deceased),Michael, Andrew,Susan and Jane. Sarah's other brother Charles Walker married a woman named Charlotte(known as Lottie),whose maiden name I do not know,and they had 2 children named Peter and Dianne If any of these names have a connection with your family tree or you know of these people,I would be very pleased to hear from you. In anticipation,Tracey.
