I NEED SOME ONE WHO IS FLUINT IN SPANISH TO HELP ME WRITE A THANK YOU LETTER TO MY NEICES AUNT IN OAXACA Mx.?

my sister went and abandoned her 6 year old daughter with her fathers family in a very poor part of oaxaca mexico a year ago ... completely abandoning her in a foreign country alone not knowing any of her fathers family or the language's spoken there. simply because she did not want her anymore , and was too spiteful to give her to any of her family here in the usa . thank fully her father's elderly sister has been nothing but loving and caring for her and eager to help us get her back home to her family in the usa who love and miss her . we have been threw a year of hell with out her here . my sister left her there with out her pass port or any of the legal paper work to get her back to the usa ... back home. this woman took her in her heart and cared for her as her own daughter . we go down to texas soon to pick her up . we cant wait to hold her and hug her again . if anyone who can write spanish , we would love to write her a heartfelt thank you note ... for everything she has done for her niece. thank you SO much .
