Puzzle 174: Eliza Pseudonym of Puzzlania 9

There is no subliminal advertising here. None at all. This puzzle is not based on a real puzzlers' league. I am not being sarcastic.

Please note that clues 5 and 6 have the word NOT in them. Failure to notice this word will yield much confusion. (Why am I pointing this out? I dunno. I guess I'm just paranoid that the word NOT will be easily overlooked otherwise.)

Rules of Eliza Pseudonym of Puzzlania

Eliza Pseudonym has recently joined an organization known as the League of Puzzlers of the Nation (LPN). Upon joining the LPN, a member selects his or her own nom de guerre by which they are known within the League. Eliza Pseudonym opted simply for Elipse, the first three letters of her first name and the first three letters of her last name. Since joining the LPN, Eliza has become acquainted with five other members, each of whom has been a member of the LPN for a different amount of time, and each of whom has also provided Eliza with hours of amusing conversations and wordplay! From the clues below, identify these other five LPN members by nom de guerre, first name (one first name is Mario), and last name (one last name is Washington), and determine how long each has been a member (1 year, 2 years, 3 years, 4 years, or 6 years).

1. The one with the nom of Grabby has been a member of the LPN for precisely half as long as the one named Moira Jackson has.
2. The member whose first name is Bob has been in the LPN for precisely one year longer than the one with the nom Ironhorn.
3. The individual surnamed Hamilton has been a member of the LPN for precisely three times as long as the one surnamed Lincoln.
4. The person whose nom is Kinship (who has been in the LPN for 2 years) and the one whose last name is Jefferson have first names which are composed of the same letters, but in a different order.
5. The woman with the first name Dolly and the person who goes by the nom of Missyl have NOT been members of the League for a combined total of precisely 7 years.
6. The LPNer whose nom is ACAB/H has NOT been a member of the LPN for precisely twice as long as or precisely half as long as the person with the first name Lloyd.
