Hyphenated surnames and official records

I recently encounterd confusion with a hyphenated surname. I had it on
good authority that the name was 'Shilton-Bratt'. When I eventually
found some references it was as 'xxx Shilton Bratt' where Shilton was a
forename. Despite this, both Shilton and Bratt families are involved.
Can anyone throw some light on the difference - why has part of the
hyphenated surname become a forename in various records. To what extent
do hyphenated surnames survive into official records?

Hyphenating surnames is a comparatively recent thing, I believe, so
the further back you go the less likely you are to find them
hyphenated. Also, you can't hear a hyphen when it's spoken unless
someone actually says "Shilton hyphen Bratt".

Burlington Bertie...

This appears a lot in my family where a child is given a middle name
which is the surname of a previous parent or grandparent. However I
guess it's not intended to be a surname since only some of the children
get the name, and only sometimes pass it on. It's odd to have a
christian name like Phythian or Monachty.

I've found such names very useful clues in tracing lost family
surnames. I've got one with (apparently) two such names but I haven't
traced them further back - Charlotte Atkins Burt Crouch b. 1839. At
least, I hope "Burt" was a family surname. What a cross to bear.

Double barrelled surnames with a hyphen do have a more permanent ring
to them.

The composer Samuel Coleridge Taylor (1875-1912) added a hyphen to
make his name sound posher. So did Harold Fraser Simson (1872-1944). I
suspect plenty of others have done the same.

Joe Makowiec...

Lack of a hyphen doesn't imply that it isn't a double-barreled surname.
Ralph Vaughan Williams and the Lloyd Webber family come to mind. Was the
name given in a form which would imply that only the second part was the
surname, like "Bratt, Xxx Shilton"?

Peter J Seymour...

Yes, indexed as 'Shilton' a forename and 'Bratt' surname.

It all depends on the person who is using the name at the time. I know of
families with surnames that are not hyphenated now, but were in the past.
One reason was a split in the family and each brother took half the original
name. Also in "official" documents, in the past word of mouth was the way
information was passed on (ie to census takers, parish priests, etc) and
written down. It's possible the person passing on the information couldn't
read and therefore wouldn't know it was documented wrongly.
In research I've done in my own family, I've found 3 different spellings, no
doubt caused by mishearing the name.
