I have been doing an ONS for several years now, and I'm still undecided on how much detail to record for spouses and family groups with different names. Most of my time is spent constructing trees from raw data by entering data into Family Historian. 1. For children, I generally do one generation, since the children's mother is a Skyrme. I create new records for them but I am ambivalent about how much detail I include beyond their birth dates. I enter all the facts I find for the mother (census details etc) until her death, but not for her husband if he outlives her. 2. For spouses, of either a male or female, I try to track them from birth. I create records for their parents, and try to find their birth and death dates. For siblings, however, I just tend to make a note in the family group record, e.g. listing those found in censuses alongside estimated birth year rather than add detail of their baptisms, occupations etc. So my approach is one generation up, one down, but with an inconsistent approach as to which records to create (vs. just a note) and what facts to include for the person whose birth name is not Skyrme. I'd be interested in how others restrict their scope.
