Wight Family Geneology

I am looking for information about my great great grandfather.  He sired Henry Lucien Wight in 1854 who wed Emma Florence Christiana in 1878,  She bore him 2 daughters, Ivy and Ruby, and 1 son, John C****** Wight (my grandfather).  My great uncle is E. D. Wight, Postmaster.

Henry Wight died in 1896, a member of the Masons.  Family legend is that Emma traveled to Scotland with the 3 children shortly thereafter.  Both girls were enrolled in boarding school in London - St. James.  We have been unable to gather matriculation information for John until 1907. 

I would appreciate any information.  Thank you.
