Hi, Richard, Your Kroeker data sounds impressive. I've been up the proverbial tree for quite some time when it comes to my Kroeker ancestors.
Have you got a Gerhard Kroeker & Anna Nickel in there? (both born about 1825). I'm aware of some children, but there may have been more. David (b.2/12/1863) md. Maria Hiebert (b.11/14/1861) Anna (b.7/221857) md. Heinrich Braun (b.5/27/1852) Peter (b.11/24/1860) md. Helena Siemens (b.11/24/1865) and a Gerhard who also came to Canada, but then later moved on to Mexico.
I come from David's line, as that was my great-grandfather, and I have his descendants quite thoroughly, but would love to have more on his ancestors earlier on.
