Hej to everyone
Because of all the information and advice you have given me, I have worked out that Sophia is the daughter of Iver Broager and Kirstine Margrethe Peddersdatter. Iver was a præst at Tim and later at Staby where he died in 1749. I found the following information on Erik Brejl's site:-
Iver [Nikolaj Lorentsen] Broager, præst i Staby, død marts 1749.
E: Kirstine Margrethe Pedersdatter [Stavning]. B:
1) Lorents Peder Nikolaj
2) Frands Linde
3) Johan Leonhart
4) Sofie Cecilie Hedvig.
Sophia had a daughter Kirstine Margrethe born at Holstebro 19/3/1773 - 1762-1815 ops 30, by her first husband Søren Poesgaard who died 6/1/1774 - 1765-1815 ops 31.
In the 1787 census in the house of Johan Leonhart Broagger at Ringkøbing it shows:-
Kirstine Margrethe 10 Ugift Hosbondens Søsterdatter
and at the same address in 1801:-
Kirstine Magrethe Porsgaard 27 Ugift en søsterdatter af manden [Johann Leonhardt Broagger]
This should be sufficient proof that Sophia is the daughter of Iver Broager and Kirstine Magrethe. Tell me if you disagreee.
I still have to fine her birth place.
Thanks and best wishes
