I am traveling to Luxembourg early July for 4 days to find ancestoral graves near/around Holzem & Koerich. First, we are looking for WEILAND (family name) relatives. Second, is there a "guide" we could hire to navigate around Luxembourg and look for ancestoral graces and/or living relatives. Third, can you refer some country villa or hotel for 5 (including a 2 & 5 year old)? Finally, advice on renting a car to travel around luxembourg--is it easy to navigate? What do you recc we see in 4 days? THANK YOU!
