I got interested back in the 1950's and 1960' by attending the Rosenquist reunion that started in 1942 by the descendants of Andrew Rosenquist and added the descendants of Swan Rosenquist in the 1950's.Very early on they put together a 
scrapbook for this descendants. Alfred Rosenquist who immigrated in 1866 wrote what 
he was tolded. Andrew, his wife Sissela and Alfred Rosenquist;(his brother) Nils and 
wife Boel,(four children) Elna, Erland (Arland),Martin, and Johanna Rosenquist; 
(sister) Mary who married Peter T. Peterson of Afton Township; and (half  brother)
Sven (Swan) Rosenquist came in 1866. They were in New York on 3 Jul 1866 landed on the
5 Jul 1866. They came to Afton Township, Washington Co.,Minnesota,USA to Uncle Sven Rosenquist and  Uncle John Rosenquist farms. Swan went on to St. Paul, Ramsey Co., Minnesota, USA and married Ellen Mattson on 29 Aug 1867 in  Ramsey Co., Minnesota, 
USA. Nils went on to Svea, Kandiyohi Co, Minnesota, USA where Mathilda was born on
11 Dec 1866. They left (half sister) Elna Persson (26 years) , (half brother) Per Persson (20 years),(half brother) Magnus Persson (16 years), (half sister) Pernilla
(13 years) who was dear and dumb, (father) Pehr Michaelsson (65 years), and (step-
mother) Svenborg Svensdotter (49 years) in Spragleröd, Brönnestad, Skåne Län, Sweden. 
        I used the Rosenquist book and 3 scrapbooks to start on my dad's side. I 
started to do research  in the Swedish records in 1977 by writing to Lund, Skåne Län, Sweden to find the parents of Andrew. They wrote back that about Andrew,  his parents, and list of some of his siblings. Then I started to do my own Swedish research at the Rockford Illinois Family History Center in 1978 and joined the staff in 1981. I found
that Elna Persson Månsson in , Brönnestad, Skåne Län, Sweden; Per Persson in Sandåkra, Norra Mellby, Skåne Län, Sweden; and Magnus Persson in Sandåkra, Norra Mellby, Skåne Län, Sweden. I found out that he also had (uncle) Nils Michaelsson last known in 1827 
in Ingaberga, Skåne Län, Sweden  ;(uncle) Måns Michaelsson Rosenquist Sweden last 
known in 1854 coming to USA but his daughter Augusta Rosenquist came in 1867 with 
her son Herman to St. Paul, Ramsey Co., Minnesota. ;(uncle) Petter Rosenquist (Pehr 
Michaelsson) who died in 1857 , Norrköping, Östergötlands, Sweden but his children:  Clara Josephina Rosenquist Envall of , Tuna, Kalmer Län, Sweden , Patrick Gottard Rosenquist of , Maria, Stockholm, Sweden, and Edward Mauritz Rosenquist last known as 
of , Karlstad, Karlstad Län, Sweden;(aunt) Elna Michaelsdotter in  Brönnestad, Skåne Län, Sweden  ;(aunt) Elna Michaelsdotter Liljeroth in  Lund, Skåne Län, Sweden; and (uncle) Pal Michaelsson in Stoby, Skåne Län, Sweden. I found that Andrew  had a son
Nils Anderssén 18 Jun 1858 in Kialt #2, Vinslöv, Skåne Län, Sweden. He came to Warren Co, Illinois, USA in 1881. After I found this out my Father remembers meeting his 
uncle and sons in Eagle Bend, Todd Co, Minnesota, USA in 1910’s. Also Uncle Bernard
and Marie a cousin said the same thing.
