My name is Teri and I hope I have the right person.I saw your post on Genealogy.com for Daniel Lachat of Lock Haven, PA and he in fact is my great grandfather!
My great grandmother Mary Pauline Lachat was his daughter - In turn, also my grandmother Marion Coleman Bongardt was his granddaughter.
I would love to chat with you as I have many census records for the Lachat family and I can tell you that their name over the years has been botched up nearly every single time :-)
Daniel is the son of George and Marie Catherine Lachat - whom were originally from Switzerland.They came to America in 1852 and resided in Louisville, Ohio when first arrived and then moved onto Clearfield, PA and then Lock Haven, PA.
Someone mentioned Alexander to you and he in fact was the oldest son in this Lachat family.They went on to have a total of seven children - Daniel being the second oldest and most of them went on to Pennsylvania.
Please let me know if you get my message as I would love to connect with you!Have a nice day :-)
