Thank you everybody for the efforts- great. The bride and Groom are my grandparents. Best man is his brother George. The couple in front to the left are my great grandparents and, we think - but are not too sure- that the old guy at the back with the bushy white beard is my great-great Grandfather. Grandad (the groom) had 4 sisters and 4 brothers. The two bridesmaids at the front are - again we think!- his sisters. The lad immediately behind the groom is one of his brothers and the lad right at the back to the right is another brother. Photograph taken 4th April 1904. This may answer one of the queries posted by Emmeline.
The family are still working it all out!
