Sorry to take so long to get back to you. Vacation and computer problems.
I have a Carl Johann Albrecht b. about 1810, married to a Johanne Sophia Juliane Tychi, b. 1816-1817. They had several children including Anna and Ida who married brothers, Friederich and Georg Sharnberg, respectively. The full name is Anna Friederike Albrecht, b. February 28, 1845. Anna is buried in Shelby, (Austin) Texas along side her husband.
Does this match your ancestors? If you would like more information on the siblings and when the Albrechts came to the US, send me an email and I can provide this for you.
