Hi I am looking to find my great great granddads Father and Mother. My my g,g granddad was named William Miller he was born about 1805, I don't know if he was married before he lived with his partner Helen Mcfarlane she was married before to Alexander Muggoch (could not find any marriage certificate for her and William). William's sons:- my great grandad Robert born 1851 James born 1855 Alexander born 1858 Peter born 1860. Hope someone can help have been looking for some time now. Thanks

Miller
