The 1911 census in Surrey used first name initials on the page I found a G Henwood. Surrey is a neighbor of Hampshire where I have found most Henwoods. The G could be for a George, Gerald. He had 4 males and 5 females in the family at Dahlia Cottage in Farnham, Surrey, England. The others were not listed, only the head of the family and type of structure. That's 9 people living in a cottage.
