Hi Pam,
I found 2 places named Walde in Prussia:
1. Walde area of Posen, district Bromberg
2. Walde, Colony part of Groditz, district Falkenberg.
There is also a place called Trischin (may be you misread this as Trifsia)
it is in the area of Posen, district Bromberg.
all three were in Prussia and are Polish today.
Both Walde and Trischin belonged to Land Preussen, Provinz Posen,
Regierungsbezirk Bromberg (see
