Taking this back one generation it gets quite interesting

THe IGI gives an extracted mariage entry for an Isaac Austin to Mary Ann Wall, 1/5/1823, Tonbridge, Kent.
The 1851 census has Isaac at Tunbridge High St
Isaac Austen mar 53 Grocer b. Brenchley, Kent
He has 6 employees for his grocery business & 2 house servants.
Mary Ann turns up back in Godalming in 1851,
Mary Ann Austen wife 46 Grocers wife b. Tonbridge, Kent
Selina dau 7 b. Godalming, Sry
Arthur son 4 ditto
4 employed in the grocery & 3 house servants.
Looks as if they are running two grocery businesses, one in Godalming & one in Tonbridge. That being the case there should be more documentation about the family.
There is a death on FreeBMD for an Isaac Austen Q3 1857, Tunbridge. This is probably him as the TNA has a will for Isaac Austen, grocer of Tonbridge, Kent, 3/11/1857. This can be downloaded for 3.50 pounds.
By 1861 Mary Ann is widowed & seems to have moved up to Warwickshire where she's a shop keeper.
I've just looked at the public trees on Ancestry & found someone has already researched this family

Of course this all has to be double checked;
Isaac's father was John Austen (1758-1820) born Brenchley, Kent. He married Sarah Martin, 1791, Sussex, Delaware, USA.
John's father was another John Austen (1726-1795) born Brenchley. He married Elizabeth Balcombe. This John died 1795, Deer Creek, Hartford co. Maryland. So, many connections with the USA!
If you don't have access to Ancestry but would like to contact this researcher let me know & I'll try to contact him,
