I am assuming that your grandmother's given name is "Estadr" and that
"-dr" is used as an abbreviation of "-dotter", meaning "daughter of".
"Estadr" would then mean "daughter of Esta".
There is very little information about the name "Esta" on the web -
most of it points to the fact that it means "from the east" in
Italian. I looked up "Esta" in a Norwegian "name encyclopedia", here
Esta was listed as a short form of "Ester" ("Esta" sounds very much
the same as "Ester" when pronounced in Swedish). Ester/Esther is a
very common name in Scandinavia, especially in Sweden.
A Swedish web site (http://www.svenskanamn.se/name_page.asp?name=Ester)
gives this description of the name "Ester":
"Ester is on the way back to its former top placement on the list of
popular Swedish first names. 20 years ago, Ester was still the 40th
most common female name, but its figures dropped sharply when most of
the women born in the 1800's had died. Among youger Swedes, Ester is
now on the rise. During the 90's its popularity multiplied, and
by the start of the new millennium Ester was among the 150 most common
names in Sweden.
Ester har been used as a Christian name in Sweden since the 15th
century. During the 17th century Ester replaced the older Swedish
name "Estrid". "Ester" derives from the persian word "stara", meaning
"star". Ester has had an official "name day" in Sweden since 1901,
replacing Amos place in the almanac."
(The name "Estrid" is not related to "Ester" - "Estrid" is an old
Nordic name meaning "bautiful goddess". "Estrid" is not used much
today, but its close relative "Astrid" is in common use in
Apart from its Persian meaning of "star", some web pages translates
Est(h)er as "myrtle leaf" (Persian) and "secret" (Hebrew). The web
site behindthename.com has these descriptions for "Esta", "Ester" and

Possibly means "star" in Persian. Alternatively it could be a Hebrew
form of ISHTAR, the name of a Persian goddess. The Book of Esther in
the Old Testament tells of Queen Esther, the Jewish wife of the king
of Persia, who saves many Jews from persecution."
The current Swedish use of the names above are as follows:
14194 Swedish women are called "Ester"
1158 Swedish women are called "Esther"
17 Swedish women are called "Esta"
1 Swedish woman is called "Este"
You might also like to know that the surname "Lovestrome" is not used
at all in Sweden today. "Lovestrome" is probably a transcription of
"Lövström"/"Löfström", which is used by 417/1058 people in Sweden.
