My thanks to this community and those who, with, or without, hesitation, ask questions, and those who answer without hesitation. It is because of this, I have been able to properly store three generations of a family collection, in a short period of time.
wt1 posted a link to '
Cancellations and Killers of the Banknote Era' and it is to this, I address my first question on this forum. Thank you, for that link, wt1. It was a great help and a fascinating look, that addresses where a stamp might have come from.
My first question is about the hand stamp town cancel in the photo below. I would welcome the opportunity to learn more, by the community's input, whatever it may be, regarding the cancel. It appears, to me, close to, but not an exact match, to the 'HP' in the Holland Patent, NY cancel, (page 121, I think) from the link wt1 posted. I understand I may never know exactly where it is from, but on the off chance someone recognizes it, or has some possible idea of where to look, besides the link, it would be greatly appreciated.

I also am posting two other postmarks I would like to learn about. The stamps with the blue cancels, (or are they purple?) what, if any, significance, does a blue cancel have, as opposed to a black cancel? Are they parcel post? Forgive me, if this a repeated question you've answered over and over again. I, myself, haven't been able to find the answer, easily.

The last postmark, (is this also a parcel post?) all I can read is the letters 'TUCKET'. It's possible it
might either be Pawtucket, or Nantucket. I'm hoping someone has the full cancel, or recognizes it.

The majority of the collections' classic stamps, were collected by my great grandfather, who lived in the New England area. I do not automatically assume all the postmarks will be from that part of the country/world. By the same token, I do not rule it out, either. So far, the ones I can identify are. I mention this, as it could be 'a place to start'.
I've not removed these stamps from the paper they are on, since the postmark is what I'm interested in, and they lap over onto the paper. The stamps are common Scott #220, no caps.
Thank you, in advance, for your time, and assistance.
