We have very little information on Maria Kruiske except that one of her children was born in 1839 which suggests she was born early 1800's.The family seems to be German descendants and there are many Manthey descendants living in or around Lowood/Laidley Queensland Australia. There is also links with the Pomerenke family here in Australia. Other surnames in this family tree include Jeske& Robeck. Any information would be appreciated. Thanks Fiona.
