Cornelis Vlieland of Kees Vrijland

We know Cornelis Vlieland went missing in 1796 .

His daughter needed his consent on her wedding and  had to certify that he was missing by the statement of several persons that knew her father well.

We know a man named Kees Vrijland was a prisoner of war at that time in Chatham.

You may think  the names are not the same ,but in Holland Kees and Cornelis are the same .

Sometimes the name Cornelis is used in official document and Kees is the name used everyday.

The name Vlieland was pronounced and written down by a clerck ,who wrote it down as it was pronounced. So this could be our Cornelis . The next entry as a prisoner of war is Arry Vrijland .

Same story .Arrie must be Arie Vrijland .

So he died in hospital but so far we did not find Cornelis 

They were not the only  prisoners of war.

Between 1793 and 1815 approximately one-quarter of a million prisoners of war were held in Britain.
At Chatham between 1803 and 1814 there were approximately 90,000;at Plymouth between 1793 and 1814, about 175,000; and at Portsmouth for the same period, approximately 360,000. At any one time there were thousands of prisoners confined in these areas and many more at other ports. Yarmouth held approximately 38,000, and Bristol and Liverpool about 40,000 each
Systems for the humane treatment and exchange of prisoners had evolved during earlier eighteenth-century wars.
