this appears to have been a either a beginner's effort for someone or more likely a combination effort. it was very common in former decades for friends or family members to help piece...however, you can see the pitfalls if everyone is not using the exact seam allowances... i think the blocks simply did not match and a way was found to use them and not lose all the work that went into them... the block is simply a quarter circle with a pieced strip in it...it may have been supposed to be part of a double wedding ring or used in a one of the many drunkard's path layouts... there are block names and layout names and a block can be used in many layouts... this may or may not have had a name in the beginning, but the lack of the matching sizes gave it a new twist....it doesn't really matter, it is lovely and should be enjoyed...it's hard to date from the fabrics as the pics/prints are small, but the fact that it was white rather than muslin tells you it was meant to be a 'good' quilt (in addition to how good the condition is, clearly not used a lot)...white was more expensive and not usually used for 'everyday' quilts... it appears to be old but the prints are very bright which speaks of later dyes... ticking (the tiny stripes) has been around for centuries but this is just a print, not real ticking, so no help there... rose prints, ditto...been around as long as there were prints.... the yellows speak of later...yellows were rare and expensive in early days and these are especially bright...you're gonna need a 'hands on' appraiser to give you real information on this one...congratulations on a lovely quilt whether it an antique or not....
