The majority of the Davidson patterns were given names by William "Bill" Heacock. John Bell also named a couple. There is a complete listing in my book, VASELINE GLASS: CANARY TO CONTEMPORARY, by David A. Peterson.
However, that is not a sales pitch, and can provide names as they relate to registration numbers:
There are also a couple other pieces made in Primrose Pearline (past the date that is commonly used - 1903) as the last time that Davidson supposedly made Primrose Pearline. Those will be at the end of this post. Those have not all been given any generic names.
IN ORDER BY DATE OF REGISTRATION, DATE OF REGISTRATION AND GENERIC NAMES:
RD 96945, 3/31/1888 RICHELIEU
RD 130641 TO 130643, 8/13/1889 BRIDESHEAD
No Rd. number: 1890 SUITE, advertisement shown in Pottery Gazette on 4/1/1893, also known as PRINCESS DIANA.
NO REGISTRATION: LADY CAROLINE, circa 1891, also known as 1891 SUITE
RD 176566, 8/15/1891 LADY CHIPPENDALE
RD 193365, 6/1/1892. Heacock called it DOVER DIAMOND, John Bell named it ASHLEIGH. ASHLEIGH seems to be more recognizable. This is probably the toughest pattern to find, in any shape, in Primrose Pearline. I know of two bowls.
RD 212684, 5/25/1893 WAR OF THE ROSES (6 BOAT SHAPES)
RD 217752, 9/6/1893 PRINCE WILLIAM
RD 237038, 8/1/1894 LINKING RINGS
RD 254027, 5/1/1895 SOMERSET

RD 320124, 6/10/1898 QUEENS CROWN
RD 413701, 7/14/1903 WILLIAM & MARY
ALSO: NO REGISTRATION, but referred to in old literature as pattern No. 900, introduced in 1893: QUILTED PILLOW SHAM.
HELEN LOUISE, not registered, unknown year of production, named by John Bell in honor of Helen Louise Bennett, his significant other. It resembles closely BRIDESHEAD, but is different, and is only known in a cream and sugar. unmarked.
Also, John Bell found a Davidson catalog, dated 1912, that showed various pieces of an ice cream service.
this piece is from that group:
http://www.vaselineglass.org/davidsonicecream.jpg I also have this dish in a smaller blue opal version. There are also two considerably longer banana boat styles known in primrose pearline that have the similar shell fluting on the edge.
also: I have three small open salt dishes that are Davidson, but only one is marked.
Round, no pattern on sides, sunburst on bottom: early 1880s, shown in one of Heacock's Open salt books.
Square, no pattern on sides, sunburst on bottom: Rd. 577153 (but not marked), registered 1/28/1911.
Fluted vertical sides, with solid band rim at top edge (not named), marked with RD 549518, registered 9/18/1909.
I have also seen two small berry bowls (in a double marmalade frame) in the No. 269 'Raspberry Prunt' line that are in primrose Pearline, and have a photo I can share on that one:
http://www.vaselineglass.org/davidson269opal.jpgThat is all that has been discovered so far in the Davidson line that was made in Primrose Pearline. oops, just recalled, there are a couple very older bowls that I have seen, but they were not named, and don't have any registration numbers. they were very early 1880s. it would take me a little while to dig out photos, but the pictures match a known catalog illustration.
