I have some information re William Hutchinson Hearfield as i am researching the Garniss line, (Garniss being my maiden name) and Elizabeth Garniss was the sister of my great, great grandfather. William was the son of David Hearfield and his occupation at some time was a quarry proprietor. He was christened in Hessle by Hull Yorkshire England on the 31st March 1811. He had at least one brother, David christened 6 Jun 1813. William and Elizabeth had 7 children, Mary Ann, Tace Eleanor, John Garniss, Charlotte Elizabeth, Rhoda, David and Elizabeth Kelsey, (Kelsey was Elizabeth's mother's maiden name). Tace Eleanor married Alexander Strachan in 1870, John garniss married Amelia Franks in 1877, Charlotte Elizabeth married walter Knowsley Henson in 1872 David you already know, and Elizabeth Kelsey married Albert Conyngham Bannistter in 1885. Unfortunately I don't have much more information on the Hearfields as Garniss is my main research interest. However I am prepared to try to find out more if you are interested, Hull isn't too far away.
