Sorry silly question(s). Am new to Harnesslink so please excuse my ignorance. Have asked around and not got any 'satisfactory' answers. Understand no rules to it but would appreciate your comments/answers.

1. When they say your mare is a "XX" line mare, to which line are they referring? Can draw many lines through the pedigree, but which one is the the 'line'?

2. Age. If I look at Christian Cullens pedigree (for example) I see Tar Heel back as one of his 'great grandfathers'. From what I can see he was 25 years old when he served 'In the Pockets' grand mother (Miss Skipper). Due to age, is he excluded from any 'pedigree matching'?

Sorry again to ask silly questions.
