Hi Scott,
This is one of those confusing census records you can find in these Swedish Church Books.
I think I can help clear up most of the confusion.
First of all Enkan Catharina ?Flodberg? b Jan 12, 1775 is a daughter of Petter Carlsson and Anna Persdotter.
Source of info: birth record GID: 2240.54.34800
Catharina Wilhelmina Turgren b Dec 26, 1805 in Södertälje was the daughter of Soldat Per Turgren and Catharina ?Flodberg? b Jan 12, 1775 in Ekeberget.
Source of info: birth record GID: 2462.15.67800.
Soldat Per Turgren was b abt 1767 in
, d Mar 29, 1810, buried Mar 31, 1810 in Södertälje, Death record says he died of ?influenza?, 43 yrs and one day old.
Source of info: death record GID: 2462.15.80500
I have not been able to find out how or when Catharina b 1775 got her last name and I'm not sure of the spelling either but her last name is written much clearer in Catharina Wilhelmina's birth record at GID: 2462.15.67800. Maybe someone else can help with the correct spelling.
Have a nice day!
Don
