Catching up with the thread!
I am 40s, London based, come from a solidly royalist family and have followed the royals since the Diana years. It was an interest I shared with DM and I can remember reading out the Camillagate phone conversation in full to her, putting on special voices for Charles and Camilla! Sadly DM died when I was in my teens, so I could empathise with W&H's loss at a similar age.
I am still royalist, and that is not likely to change during the Queen's reign. After that all bets are off, although I am one who thinks Charles can make a success of the top job.
Love the Cambridges' Xmas photo. You can see the affection between George and William. Charlotte is so confident in front of the camera, she puts me in mind of childhood photos of Diana. Louis melts my heart every time I look at him! Have never taken to a royal baby like this before, and photos of relatives' babies generally leave me cold, so I don't know what it is, he is just special. 
Kate has been my biggest influence in recent years. While much of her wardrobe is beyond my means, I do own two Buckley poppy brooches and was overjoyed this week to find a pair of Air Force blue leather gloves to match my Air Force blue handbag.
