If for a native the exact birth time is not known for deriving the lagna, dates of some important life events are used to match with the dasa and antardasa running at the time and we try to estimate the lagna.
In addition to matching the life events of the native, horoscope of the brothers, sisters, parents and children whose accurate birth time is available will help in fixing the lagna of the native. In this regard i can say there will sure be a common point in the horoscope of the family members. Like for example, placement of Rahu- Ketu. If one of the coborns has Rahu-Ketu axis in the lagna, then in all probability the native whose lagna is to be identified also will have the same feature of having the RK axis in the lagna. It is not necessary that the lagna is the same for both. But placement of RK axis in lagna may be the common feature in all probability.
It will be more helpful if we have more horoscope of the family members with accurate birth details. The one whose birth time is to be fixed can be done using these. Looking for common features in family horoscopes and matching the dasa and antardasa will sure help in fixing the birth time.
