Valder ancestry

[robertsteer]

I am researching the ancestry of my forebears in the name of VALDER that lived in and around Lyminge between 1780 and 1846.
JOHN VALDER born 1780 married MARY BOORN and lived in Lyminge Street. He ran a private school for navigators/gentlemen from 1811 when an article concerning this appeared in the Kentish Gazette of that year.
FREDERICK (1809-1879) son of JOHN AND MARY married MARY TAYLOR-HOGBEN (HOGBEN - a common name in the area of that time). FREDERICK worked as a schoolmaster in his fathers school and in 1851 lived at 13 Each End Hill, Lyminge.
FREDERICK and MARY had three sons all born in Lyminge - FREDERICK (1842-1923) married Elizabeth (Unknown surname) and then ANN DEAL.
JOHN (1844-1927) married SUSANNAH HYDE and
ALFRED (1846-1904) {my great great grandfather} married EMMA ANDREWS.
If anyone can fill in more details I would be most grateful.
