Dame Margaret Shields RIIP, and SHELL-TER

The Deaths in 2013 site lists under May 29th:

• Dame Margaret Shields, 71, New Zealand politician, MP for Kapiti (1981–1990), dementia and Parkinson's disease

Margaret's surname is meaningful given recent pattern-clusters that emphasize that we need to shield ourselves in a calm safe haven. The House of Names web site,  http://www.houseofnames.com/shields-family-crest, reveals the following etymology:

  the Shields name to have originated in Berwickshire and was the Middle English version of the name "schele" or "skali" which was "used first of a shepherd's summer-hut or small house."  Robbie Burns included in the line "the swallow jinkin around my shiel."

Hmmm, this is about the 4th time that Robbie Burns has cropped up in the last while.

Note the etymology of the word shield and related other words: 

shield (n.) Old English scield, scild, related to sciell (see shell), from Proto-Germanic *skeldus (cf. Old Norse skjöldr, Old Saxon skild, Middle Dutch scilt, Dutch schild, GermanSchild, Gothic skildus), from *skel- "divide, split, separate," from PIE root *(s)kel- "to cut."

 shell (n.)  Old English sciell, scill, Anglian scell "seashell, eggshell," related to Old English scealu "shell, husk," from Proto-Germanic *skaljo "divide, separate" (cf. West Frisian skyl"peel, rind," Middle Low German schelle "pod, rind, egg shell," Gothic skalja "tile"), with the notion of "covering that splits off," from PIE root *(s)kel- "to cut, cleave" (see scale (n.1)).  

scale (n.1) "skin plates on fish or snakes," c.1300, from Old French escale (12c., Modern French écale) "scale, husk," from Frankish or some other Germanic source, from Proto-Germanic *skælo "split, divide" (cf. Old High German scala "shell," Gothic skalja "tile," Old English scealu "shell, husk), from PIE root *(s)kel- "to cut, cleave, split"

 scale (v.) "to climb," late 14c., from Latin scala, from scandere "to climb" (see scan (v.)). This is also the source (perhaps via Italian scala) of the noun in the musical sense (1590s), and the meaning "proportion of a representation to the actual object" (1660s). Scale down "reduce" is attested from 1887. Scale factor is from 1948. Related:Scaled; scaling.

 scale (n2.) "pan of a balance," late 14c., earlier "drinking cup" (c.1200), from Old Norse skal "bowl, drinking cup," in plural, "weighing scale" from Proto-Germanic *skælo "split, divide" 

 skill (n.) late 12c., "power of discernment," from Old Norse skil "distinction, discernment," related to skilja (v.) "distinguish, separate," from Proto-Germanic *skaljo- "divide, separate" (cf. Middle Low German schillen "to differ;" Middle Low German, Middle Dutch schele "difference;" see shell)

The TUSSH is like a shell after all.  Nott saying that we design the specialized home exactly like the one our ancestors used during the last glacial event, butt the essentials will be the same-- a fully enclosed eco-system... a mini world if you will.
