Gerald,
I have a connection to the Peskett family in my tree, Robert Tobit Peskett is my great great grandmother's cousin's husband. Robert married Maud Mary McQueen, cousin of Alice Sarah McQueen.
Alice Sarah married Walter Howard, my great great grandfather.
Due to the unusual name of Tobit Peskett I did a search on the internet and found another tree which links in to the Tobit Peskett's that maybe of interest to you,
http://dinasgenealogy.co.uk/, this tree has Robert's sister Elizabeth Tobit Peskett marrying into the Cullham family and extends more in that direction than on the Peskett side of the family.
I have been in contact with the tree owner and they allowed me to take whatever info I wanted.
It was interesting to find out that this part of the Peskett family had several members who were in the 4th Suffolk Regiment and were in Barracks in London in some of the Censuses, which is why Arthur Ernest Tobit Peskett, mentioned in one of the replies to your post, was born in Ireland as his father George would have been stationed there in the Curragh Barracks for a while.
If you search for the Tobit Pesketts you will also find that Harry Tobit Peskett was killed in the Jervis Bay incident, where one ship saved the rest of the convoy by sacrificing itself to aid their escape from danger.
There is also a reference to the burial of George William Tobit Peskett who died in 1987 in Australia, George William is the Grandson of the George previously mentioned above, and son of George Jnr, confusing I know.
George Snr married Sarah Tobit (I think) going by the carry forward of the Tobit name although I have not been able to confirm this and according to a previous post they have a different surname for Sarah.
They had 8 children:
Robert
Elizabeth
George
Arthur Ernest
William
Agatha B
Horace
Gertrude
I have not done much research going back further into the past beyond George Snr so I hope this is helpful and maybe between us all we can fill in the blanks.
I have my tree on two sites if you are interested in looking at them, one is on
http://howardian.tribalpages.com but this is not as up to date as my main tree as it does not allow a search function for further connections and is very manual.
The other one is on Ancestry.co.uk and if you would like access I will have to invite you to it. I have been working on this one for a year and a half and it has become an addiction.
I hope all of this is of use and I look forward to keeping in touch if I find out any more info.
Happy searching.
Ian
