Did the Canonical 5 know each other

I think Kate used Kelly as a pseudonym on various ocasions I do not think this is evidence she knew MJK.

Given how close they lived from each other, the similarity of profession and habits offset against the huge number of people living in the East End and I think the conclusion must be drawn that at least some of the C5 knew ech other.

Perhaps not by name, perhaps only by site or nickname...."Oh there's dark Annie coming in Mary, she looks a right sight."....."See that Long Liz has been fighting again Kate"...."Oh Black Mary singing again, do you hear Polly?"

Yet we have no evidence any of them met, let alone knew each other but I think logic would suggest my scenario is possible, even probable.

Has anyone researched whether the 5 generally accepted victims of Jack the Ripper knew each other or had any connection?

There is evidence to suggest that Catherine Eddowes may have known Mary Jane Kelly (a pawnbrokers ticket in her possession when murdered - see below) but it is not conclusive.

Mustard tin containing two pawn tickets, One in the name of Emily Birrell, 52 White's Row, dated August 31, 9d for a man's flannel shirt. The other is in the name of Jane Kelly of 6 Dorset Street and dated September 28, 2S for a pair of men's boots. Both addresses are false.

I'm sure someone has considered this previously, but in the FAQs I found this statement:

Some theorists have suggested that the victims knew one another, though there is no evidence to support this idea. Although many of the victims did have lodgings, at various times, in the same small area of Whitechapel, it must be remembered that this district was wildly overcrowded with common lodgers – literally hundreds would huddle together in a single house, two, three or four to a bed. The possibility of course exists that two or more of the victims knew each other, but we have no reason to suspect they did.

But I haven't found any detailed consideration of whether they knew each other. Have I just missed it?
