He's my 32nd great grandfather, too. Hi, cousins! Maybe some of the ones who have him as a 20-somthing-th are confusing William Longsword, grandfather of William the Conqueror, with William Longespee, son of Henry II and Ida de Toeny. Or not. Those would also have the older William as an ancestor, since Longespee is a direct descendant of Longsword.
Here's at least one problem (but shhh, don't wave it about!)
| | | | | | | | | | | | | | | | | | | | | | | Capt William Constable LEE I, 9G Grandfather
| | | | | | | | | | | | | | | | | | | | | | | & Alice Felton LEE TATUM, 9G Grandmother
| | | | | | | | | | | | | | | | | | | | | | | | Richard Henry LEE, 8G Grandfather
| | | | | | | | | | | | | | | | | | | | | | | | & Mary Young, 8G Grandmother
No one has found *proof* that Richard "Henry" Lee m. Mary Young is a son of William "Constable" Lee (neither of them would have had middle names, by the way - that was not yet A Thing). Y-DNA research says he fits in among the "Jehu Lee" group, which might be very distant cousins of THE Lees (as in, having a common ancestor circa Bad King John or earlier).
The "Jehu Lee" group also seems to be entangled on the distaff side with the "Thomas Lee of VA" group, via the Greshams. This makes sorting out who's who a bit more complicated - and the Thomas Lees are no possible kin to THE Lees.
I'm a little late on picking up on this discussion but William Longsword was son of "Rollo" or formally Rolfr Ragnavaldsson (846-930), the Norse Jarl (Earl) who was elected Gangr for the invasion of France in 911 and the capture of seven cities all of which are now part of Normandy. The Norse people didn't use the letter "e" but guess where the word Gangster came from.
I am descended from Rollo by two ways - through his GGGGrandson William the Conqueror and through the Conqueror's second cousin Hawise, both descended from William Longsword. He is my 31GGF through the Conqueror but only my 29GGF through Hawise.
Hawise's GGGD Mahaut de Bretagne (Maud of Brittany) married Walter de Gaunt, who was descended from Charlemagne.
William "Longsword" is my 27th great grandfather.

Picking up on an older comment: the ancestry of "Rollo" has been discussed in detail here and elsewhere, with no clear conclusions. "Gangr-Hrolf" appears to be a legendary figure, possibly a "legendization" of the historical person some centuries later (even the Icelandic Sagas aren't consistent about him or his ancestry, Laxdaela giving his purported father as one Oxen-Thorir, while others report the well-established legend that he was a son of Ragnvald of More).
The oldest actual historical record of him, in Richer's chronicles, give him out as "son of Ketil" (but not Ketil Flat-nose, per chronology). This isn't *quite* contemporary with him, but not more than a generation afterward, so Richer was (choose one) a) making stuff up, b) reporting a popular rumor, c) drawing on some bit of knowledge that has since been lost.
