Hi. My mother's maiden name is Tyas and she says her grandfather was Joseph Tyas born in 1860 in Killinghurst? South Yorks. He was one of 5 brothers and two sisters Charlotte and Rhoda. My grandfather (his son) Hebert was born in Sheffield in 1888 and his family lived in the Penistone area of S Yorks. Any info/help gratefully received.
