[Ger-Poland-Volhynia] Thiede/Diekte the same?

[gswilson19 at aol.com]

I was going through the Chodecz marraige records online.  I came across one for Gottlieb Diekte (sp?) and Anna Justyna Maertin.

In my family tree I have Gottlieb Thiede married to Anna Justyne Maertin with a reference I am pretty sure I got for SGGEE of 8 Nov 1818, Chodecz   1818 #34..   Is Gottlieb Diekte also know as Thiede?   Could this be the correct couple?
