Hi Norair:
Thanks for making contact. And welcome to the forum. I'm afraid I have not come across a Smith Hemmings in my diggings so far, so I am afraid I am not able to draw any connections. I can see your Smith Hemmings, 28, in the 1911 Census in Northampton living with his wife Barbara and children Walter, George and Lizzie. In 1891, Smith is recorded as the son of John & Ann Hemmings. Your family appears to come from Fenton Staffordshire.
Regards, rthom
