Geoprofile of Jack the Ripper reveals Tabram and Nichols connection.

And that she came from France.
But well I know,
She came from Bow,
We used to call her Nance."

The overall attack on Tabram comprised 39 stab-wounds directed, not just to "other areas", but specifically to the throat, chest and upper part of the abdomen around the stomach. There were absolutely NO cuts elsewhere.
The overall attack on Nichols comprised a deeply cut throat and a comparatively low** number of cuts through the abdominal wall, including the lower abdomen.

** i.e. much less than 39.
It jolly well should make a difference, when one considers the details rather than high-level generalisations.Compared to the other wounds inflicted, I don't see much evidence of an interest in the private parts of either woman. If we can discern any interest, it's that Nichols' killer was interested in cutting the abdomen open, and Tabram's was interested in repeatedly stabbing the upper half of her body.
Indeed, which is why we should "interest" ourselves in the specifics.

Nothing much new there, Gareth. I know full well what the differences were - but that does not alter that there was a similarity in how both womens private parts were wounded by way of knife.

Mary, Mary Anne (Polly), Elizabeth and Catherine were all common names.

As was Kelly as an alias.

They have to be common names in the hypothesis and several of those common names obviously aren't Connolly. Hence the number of murdered unfortunates with the similar names.

Most people get that close to evisceration? Brrrr!!

It's a harsh world out there!

Apparently! Looking over my shoulder constantly now ...

We don't know exactly how, though, as there's not much detail on record. Be that as it may, it would be entirely wrong to say that the killer showed an "interest" in the private parts, when the focus of the overwhelming majority of the wounds lay elsewhere, and were very different in nature.

Actually no. An interest is an interest, regardless of whether it is smaller than another interest. As such, I think that if the whole body had been covered in stabs and cuts, it would eradicate any possibility to discern varying interests. But with isolated cutting/stabbing to the private parts, the message is easy enough to read.
Not that it alters the value of your point - it is apparent that the overall interest involves a lot more than the private parts.

The thing is we don`t really see this stab or cut to the privates occurring elsewhere in such profusion other than this spike in this district.

But we don't see a profusion of stabs in any victim other than Tabram; and it's simply a vast profusion in her case, never to be repeated in the canonical murders. Even with Nichols, who sustained two stabs to her private parts, Spratling specifically describes them as "small", which doesn't sound much like the completely OTT manner in which Tabram's killer set about his business. It's as if her killer got into stabbing in a big way, in which case it's a bit puzzling that stab wounds featured so rarely in the canonical Ripper murders and, when they did, they were distinctly minor in nature.

[Sam Flynn]

Actually no. An interest is an interest, regardless of whether it is smaller than another interest.

Nichols' killer was working away with his knife on the lower abdomen, and inflicted only two small stabs on her private area, so it's possible that these wounds were incidental and needn't betoken an interest as such.

As we don't know the precise details of either victim's "private" wounds due to the poverty of our sources, we need to tread carefully.

Doesn´t avoiding throwing the potentially very vital implications away for no good reason at all belong to that wish to tread carefully, Gareth?

Why one cut among nearly forty stabs to the upper body should be considered "potentially vital" escapes me.

[Batman]

Tabram's murder was a Lust crime. It would be classed as such today. JtR's victims are victims of Lust crimes. Same victimology. Time and location. Lust crime.

There is nothing pointing away from Tabram being by the hand of JtR. She even fits chronologically with the escalation.

[Fisherman]

Why one cut among nearly forty stabs to the upper body should be considered "potentially vital" escapes me.

Because it preceded other knife wounds to the same area on another victim of the same victimology who fell prey in the same area of the East End but a couple of weeks later.

You see, the general idea is to think "If the FIRST victim had the private parts wounded by way of knife, and if that happened to the second victim too, then it could be that the same killer lies behind BOTH murders.

But you would not think that? You would think "Since there are many more wounds to other areas of the body, that means that the similarity of both victims having had their private parts subjected to knife violence is of no importance"?

Coincidentally, Pearly Poll's husband attacked a young girl named Millicent. She was from Cable Street, I believe.
