Frank is thought to be the son of James and Jessie (nee Day) Hillier and to have been born in Headington, Oxford in 1887.
James was a Boot Maker and in 1891 was living Finborough Road, Kensington, with his wife Jessie and three children. Frank was not with them and has not been traced on that census. In 1901 he is at 17 Railway Street, Hertford, the home of Mary Taylor, 59. Widow, Publican, described as her Nephew. His sister Minnie is also there along with two of Mary’s children. On the 1911 census Frank is at 356 Kings Road, Chelsea, described as a Barman, the home of Eliza Gillet 59, Widow, Shopkeeper, together with Edward Ablett 30, a Cook.
Frank may have lived in Croxley Green for a while between 1911 and 1915.
Recorded as enlisting in Wandsworth, Surrey.
