i can help u to get in touch with Leung sifu, i am sure he will be pleased to see somebody from the "family".
anyway, u know that in our family Wong Lei is regarded as student of Lam Jou (not only by Lam family, but also by other stdents of Wong Lei, Leung sifu as well; just a statement, i know that in your family he is regarded as student of Lam Saiwing, and have no problem with that- one family, different stories/point of view, no prob). Leung sifus sets and way he moves are almost the same as we do it, with just few details different here and there, but really few. he teaches two sets that he has picked up from others (Leung Winghang, Bun Gwaiyat), buttefly palm and mui fa kyun, plus the "night tiger emerges from the forest" - my sigung does not know/teaches these.
i have some footage of leung sifu, damn, i have really tight schedule right now, but i will definitely post it here on the server.
here are some pics containing Wong Lei as well:
