The Orgar, Orger, Augar, Auger and other similar names all seem to originate around the Norfolk, Suffolk or Kent areas.
There are plenty of instances where the names have been mispelt or misread by clerics, recorders and researchers and you have Brothers and Sisters spelling the Surname differently, with subsequent generations falling into what seems like new Family groups.
There is also Earl Orgar (Ordgar, Orgard) of Devon whose Daughter Elfrida married The King,Edgar The Peaceful and who then allegedly killed the Kings son by his previous marriage to put her own son on the throne.
Then there is the Registration district of St Martin Orgar in London which lasted for around 800 years. How did the Church and district become so named. Lots of theories but very little evidence. And did The Rhyme Orange and Lemons, grow up around the church of St Martin Orgar and St Clements which were united after the Great fire of London where the church of St Martin Orgar in Cannon Street was mostly destroyed.
The Main Church was finally demolished in 1829, but the tower was rebuilt and still exists today,although as an office and not a place of worship.
If only we could bring some of this together, maybe somebody can supply some enlightening tit bits or theories.
