McGarr's - Newcastle upon Tyne

Trying to trace my Husbands family tree. Paternal Grandmather (Kathleen) was born in N U T. Her father was a cobbler & lived in Gordon Square, Walls End. Her siblings were Betty, Evia, Mary & Robert. Pls let me know if anyone has any information - Kitty & Betty moved from N U T to Folkstone during I believe the 2nd world war.
