kasearch on Family Tree Circles

I am searching for my brother. He was born to Blanch and Horace Ahrens in New Jersey possibly at Fort Momoth where Horace would have been stationed at the time. Three of us were seperated when social services took my older sister and the brother I am hunting right before I was born. I do not want anything from him just want to know if he is alive and well and did he have a good life. I have always hunted for him in Ellenville New York where he was raised and recently got info that he might have been born while his father was stationed in the Army at Fort Momoth, New Jersey. I am now almost 65 and he would be approximately 4 or 5 years older than me. Any help would be greatly appreciated.
