Estanave Family in Guernsey

[Esme2]

Could someone help me with this search please?

It is the family of John Estanave.  He had a daughter named Martha born abt. 1801 in Guernsey.  She married in Guernsey September 12, 1821 to an Englishman named George Anderson.  They went on to have three children George born 1831, Harriet 1837 and Louise 1839 all born in Guernsey.  I would like to know more about the family and also John Estanave, his wife and if he had more children. 
I have tried to search the name Estanave on various websites but have found no other references to the name or indeed anyone other than myself researching the name.

Any help will be appreciated.

Martha .George and family in the 1841 census could only find Harriet Anderson age 17, pauper born St Peter Port Guernsey in the 1851 census at the hospital/ workhouse age out by a few years ??

Hello,

Harriett married in Woodbridge Suffolk in 1866 to George Hart.  I have no further information about George and Louisa Anderson.  The 1841 census has the family living in Bordage Street, St. Peter Port.

Thank you,
Esme

Nothing comes up with that name is that the proper way of spelling Estanave ??

It is the correct way of spelling the name as far as I am aware.  I must say I have never come across the name before.

thank you for looking
