Hi James,
Yes from everything I have looked at over the last few years that is the case,Theodosia Martha Wright (1841-1921) was the daughter of Joseph & Martha & Edward Lambert's wife.
I have tried,unsuccessfully,to trace a B/C for any of the four children of Joseph Ferdinando Wright & Martha Elizabeth Smith,although I have traced their baptism records via the Ancestry.co website. I have also traced Joseph's own baptism records on the same website &, although the record on Ancestry is recorded as Joseph Frederick,the image is clearly transcribed as Joseph Ferdinando. One of Joseph's grandsons was also named Joseph Ferdinand(o?). Joseph's (1805-1844) own parents were indeed Joseph Wright (c1770-?) & Theodosia Gillio (1772-1821) & they were married 20/12/1796 in Margate,Kent. He was recorded as a gent,a schoolmaster & clerk at various times. I have been unable to go back further than this Joseph on the Wright family tree.
Theodosia Gillio had at least four siblings on which I have some limited info. I do have quite a lot of info about her brother George William Gillio (1775-1815), who worked for the East India Company. Theodosia & George William Gillio's parents were another Joseph Gillio,(c1743-1791) & an Amelia (1744-1813). I have not been able to trace Amelia's maiden name.Joseph was a surgeon. This is as far back as I have managed to go at this point.
If you would like any further info please let me know.
Edward Walter Lambert & Theodosia Wright are my 2 x grt-grandparents. How is your friend connected to them?
Regards
Coreen.
