Anne - what excellent purchases.
You are right that the stemmed comport is Fenton's Wreath of Roses.
The second one is a great find. It's a Brockwitz bowl. The pattern is not very well known, and is sometimes referred to as Sunspray. It can also be found as part of a 3-piece epergne, with a metal base and an epergne flower holder (horn) at the top.
The ruffled edge is unusual for Brockwitz, as is the slightly thinner glass. Mostly Brockwitz Carnival is sturdier and almost always "as moulded" with no hand finishing / shaping. The Sunspray, and another slightly similar pattern (Sungold Floral), are however, known in this ruffled form.
The third item is closer to home. It's a Sowerby "Pineapple" (Sowerby's 2349) sugar.
Lovely items. Congratulations.
(I don't think the black piece is Carnival, is it?)
