i'm researching a cluster of k?lstrom's in 1890-1920 philadelphia.

charles kilstrom b:1874 d:1913
his sister theresa j carlsdotter b:1867
john carl kilstrom b:1874 d:1963
and carl alfred kallstrom b:1872
i believe, but haven't shown that they are all cousins.
i have several of their mothers:
charles/teresa-Inga Sofia Johansdotter KILSTRÖM
Birth 1835 in Länghem, Älvsborg län, sweden
and
karl johan/Carolina Wilhelmina Kihlström
Birth abt 1855 in Sweden
and carl a/Eva Kristina.

one complication is that several of them are listed in sweden as legitimate, although i think i might have one Carl A´s father is Anders
Gustav Källström.

have these potential uncle/cousins as well:
Carl Gabriel Källström was born 24 Mar, 1851 d:sweden
Karolina Charlotta Karlsdotter Källström, b Dec 31, 1862 in Eksjö, Jönköpings län, Småland

anyone have these people on their trees that can help?
also helpful would be contact with k?lstrom surnamed folks with I2a2 paternal haplogroup who can trace their ancestry to sweden.

at this point i'm hoping some collateral branch in philadelphia will find this note. (children of nils harry williams b 1925 potentially)
