Unfortunately, I know very little about the Hobday family.
Henry Walter Hobday was b. 8 July 1848 in Folkestone, Eng.He was my great grandfather on my mother's maternal side.He married Annie Saker, b.29 Nov 1852 (I believe in England, although a researcher who lives in Folkestone could not find reference to the Sakers there.
She did find a Henry, age 40 with a wife Maria, age 39, in the 1851 census in Folkestone who had a 2 year old son named Henry.I believe these are his parents.
I don't know where you reside, however if you have access to a Morman church with research facilities or the internet and can access their research program, you might try the IGL records in that location for parish records in that area.The IGL sheets I have for Hobday in England, County Kent, show an Elizabeth, daughter of William and Sarah, who was christened 16 May 1790 in Saint Lawrence (Thane).There is also an Elizabeth marrying Daniel Saunders on 28 April 1807 in Ramsgate, St Laurence.She would have been 17 then.
Sorry I couldn't be of more help.Good luck with your research.
