The party included three of Bobby's grandsons - Michael, Robert and Richard Mackman - and three great-grandchildren - Philip, Anthony and Laurence Mackman, plus Philip's fiancee Talisa Mancuso. Six of the Mackmans have flown to the UK from their base in Australia.
One of the schoolboys who helped form the Club in a meeting famously held under a gas lamp on the High Road all the way back in 1882, Bobby was our first captain and scored the Club's first recorded goal in a friendly against Grange Park on 20 November, 1883.
Bobby became Honorary Secretary in the early 1890s and was on the Club's first-ever Board of Directors in 1898. He played a key role both in taking the Club to professional status and the move from playing at Northumberland Park to the site that became White Hart Lane in 1899 - the site upon which our magnificent new stadium is now being built.

"It's amazing, I almost can't believe this is where Spurs are going to live," said Michael, Bobby's grandson.
"Perhaps I get too emotional too easily, but I do find it emotional. I always wish Bobby had lived just a couple of years more and seen the double-winning side in 1961 (he passed away in 1959) but everything is built on what he started, and built on the right foundations both in terms of the style of football and what we see today.
"I cannot even imagine what Bobby would have made of it all, it's absolutely amazing.
"Bobby never stood still. This was something he started as a schoolboy and finished up creating a limited company. He pushed for turning professional and helped establish a proper ground back in 1899, a home. And now we're here. It's fantastic, almost beyond comprehension."
